How Many Kilobytes in a Megabyte Computers & Internet / How Many Kilobytes in a Megabyte How Many Kilobytes in a Megabyte Aug 31, 2011 As you may know, the binary number system is used to measure computer data, and the bit1 is the basic unit of information in it. The bit has one of the two values, denoted by 1 or 0. Eight bits make up one byte2, which is the main element in most computer system architectures. When an average man hears the terms “kilobytes” and “megabytes” for the first time, he will probably think that they mean the following: 1 kilobyte equals to 1000 bytes 1 megabyte equals to 1 000 000 bytes So, the answer to the question, “How many kilobytes are there in a Megabyte?” seems to be obvious: 1 megabyte equals to 1000 kilobytes. But don’t jump to conclusions. For example, manufacturers of computer memory use another system. It states: 1 megabyte equals to 1024 kilobytes.

More than that, this definition is more popular nowadays. It means that 1 kilobyte is 210 bytes, which is 1024 bytes. But it uses the prefix “kilo” from the metric system, and sometimes this fact causes confusion. The IEC Definitions In 1998, the IEC (International Electrotechnical Commission)3 accepted a new international standard. It suggests replacing metric prefixes in the terms by specific ones. New variants are made up of the first syllable of the corresponding metric prefix and the syllable “bi” (contraction from “binary”). The following table presents all the IEC definitions. Term MB to KB Conversion Megabytes to Kilobytes Calculator 8,000 bits Megabytes Megabyte (MB) is a unit of transferred or stored digital information, which is extensively used in information and computer technology. In SI, one megabyte is equal to 1,000,000 bytes. At the same time, practically 1 megabyte is used as 220 B, which means 1,048,576 bytes.

Nowadays, the amount of information measured by megabytes is used for representing the size of a typical MP3 file, the size of a JPEG image, and so on. Megabyte in SI and base 10 (decimal) 1 Megabyte = 10002 bytes 1 Megabyte = 1,000,000 bytes Megabyte in base 2 (binary) 1 Megabyte = 220 bytes 1 Megabyte = 10242 bytes 1 Megabyte = 1,048,576 bytes Kilobytes Kilobyte (KB) is a common measurement unit of digital information (including text, sound, graphic, video, and other sorts of information) that equals to 1000 bytes. In practical information technology, KB is actually equal to 210 bytes, which makes it equal to 1024 bytes. Decades ago, this unit used to be one of the most popular ones, but recently, since the volumes of information increased drastically, such unit as gigabyte has become more commonly used.

Kilobyte in SI and base 10 (decimal) 1 Kilobyte = 10001 bytes 1 Kilobyte = 1000 bytes Kilobyte in base 2 (binary) 1 Kilobyte = 210 bytes 1 Kilobyte = 10241 bytes 1 Kilobyte = 1024 bytes How to Calculate Megabytes to Kilobytes Megabyte in SI 1 Megabyte = 10002 bytes We know that 1KB = 1000 bytes, so 1 byte = 1000-1 kilobytes putting 1 byte in megabyte equation; 1 Megabyte = 10002 * 1000-1 KB 1 Megabyte = 10001 Kilobytes 1 Megabyte = 1000 Kilobytes MB to KB in Base 2 Megabyte in base 2 1 Megabyte = 220 bytes 1 Megabyte = 10242 bytes 1 byte = 1024-1 KB 1 Megabyte = 10242 * 1

Have you ever tried to find out? I have. But I don't think the average person wants to sift through all those pages of technical mumbo-jumbo to find out about Bytes, Kilobytes and Megabytes. I've boiled it down to the nitty-gritty. Hopefully, this page will help you better understand how it works. First of all, you must remember that computers do not speak english. They do not string together the letters of our alphabet to make words. �They do not use our 10 decimal numbers to make endless number combinations. What computers use is a binary system of numbers to represent every little thing that you type into your file. That is how it's all stored in memory....in binary numbers. What are these binary numbers? For comparison, the decimal system that we use in our everyday life has 10 numbers, BUT the binary system has only two numbers....1 and 0. When information is stored in memory, it can only record 1's and 0's, so every byte you type is a combination of eight 1's and 0's. How is this done?

Here are some examples: The binary number for the capital letter A is 01000001 The asterisk symbol * is stored as 00101010 The name "Clinton" would look like this: 010000110110110001101001011011100111010001101111 01101110 Each letter, number, space or symbol you type is represented by a combination of eight 1's and 0's. This may seem like a waste of space, but the computer doesn't really care about space. Actually, they say that the binary system is much easier for a computer to understand because of it's electronic nature and the fact that it's only dealing with 1's and 0's. NOTE: This binary system is standard all over the world for anyone who puts information on the internet, whether it is done on a computer or done on Webtv.

There are 256 different combinations you can make with 8 zeros and ones, so it's more than enough to cover the alphabet and other characters like the ? and the @. Here is the order: 1 bit = a single digit, either 1 or 0 8 bits = 1 byte, a combination of 1's and 0's 1024 Bytes = 1 KB (kilobyte) 1024 Kilobytes = 1 MB (megabyte) 1024 Megabytes = 1 GB (gigabyte) Another way to put it: You are allowed a total of 1024 bytes before you use up one KB. And you can use over 1 MILLION bytes (1024 X 1024) before you use up one MB. And you can use over 1 BILLION bytes (1024 X 1024 X 1024) before you use up one GB.

Or think of it this way: Bytes make up Kilobytes of 1024 which make up Megabytes of 1024 X 1024 which make up Gigabytes of 1024 X 1024 X 1024 Any way you look at it, it all comes out the same. Now to explain how they get that magic number 1024. Because the binary code system has only 2 numbers, powers of 2 plays an important role. Numbers always have to be 2 to the power of ???. They take 2 to the 10th power to get the number 1024. For those of us who are not very good at math, I'll spell it out for you.

2 is the 1st power 2 X 2 = 4���(the 2nd power) 2 X 4 = 8���(the 3rd power) 2 X 8 = 16���(the 4th power) 2 X 16 = 32���(the 5th power) 2 X 32 = 64���(the 6th power) 2 X 64 = 128���(the 7th power) 2 X 128 = 256���(the 8th power) 2 X 256 = 512���(the 9th power) 2 X 512 = 1024���(the 10th power) And that's how you get 1 KB. If it's easier for you to "estimate" your usage by using 1000, go ahead and do it. Remember that your "actual bytes" will differ from the "rough size" you'll get because text is not the only information that takes up room in your storage.

Images and Midis are recorded in bytes as well as codes such as Bold, Italics, Underline, different Fonts and Font sizes. These all add bytes to your pages. If you don't understand any of this, don't worry. In the long run, it shouldn't really matter too much because the computer keeps pretty good track of all your bytes for you. Go into your file manager and you'll see the sizes listed right there for every page you make and for every midi and image you have in your directories. FYI, this page used up only 6 KB of space. Honest. It says so in my file manager. That means I can make over 200 more pages just like this one before I use up even one MB. But who's counting, right?

You are here: Help > Computer Storage How much is 1 byte, kilobyte, megabyte, gigabyte, etc.? Below is a list of each of the accepted disk drive space values.

It is important to realize that not all manufacturers and developers use binary base 2. For example, a manufacturer may list a product's capacity as one gigabyte (1,000,000,000 bytes, a metric value) and not 1,073,741,824 bytes ( gibibyte ) that it actually is. For this page, we are using the "common names" and listing all values in base 2. Note: All values are whole numbers , which means a GB shows it can only contain one 650MB CD, but 1GB could hold 1.5753... of a 650MB CD. Since we created this document to illustrate how much each value can contain in whole, no decimal values are shown. In other words, you can only fit one complete 650MB CD on a 1GB drive since two full 650MB discs exceed 1GB. Tip: With the exception of a bit and a nibble, all values explained below are in bytes and not bits. For example, a Kilobyte (KiB) is different than a Kilobit (Kb).

When referring to storage, bytes are used. When referring to transmission speeds, bits are used. Bit A bit is a value of either a 1 or 0 (on or off). Nibble A Nibble is 4 bits. Byte Today, a Byte is 8 bits. 1 character , e.g. "a", is one byte. Kilobyte (KB) A Kilobyte is 1,024 bytes. 2 or 3 paragraphs of text.

?

As of 2015, there are no approved standard sizes for anything bigger than a Yottabyte. However, the two standards that have been proposed are the Hellabyte or Brontobyte . How are you calculating the above values? Calculating the above values is simple once you know the values of each of the above sizes. For example, in the Gigabyte section above, we know that 1 gigabyte is equal to 1,024 Megabytes. Therefore to determine how many 4MB MP3 files are in a Gigabyte, we take 1,024 / 4 which equals 256 or 256 4MB MP3 files in one gigabyte. Tip: You can also use our search engine to search engine and our conversion tool also to convert and compare between values.

SmartFTP - Bits, Bytes, Mega, Giga, Tera (explained) Bits, Bytes, Mega, Giga, Tera (explained) 1 bit = a 1 or 0 (b) 4 bits = 1 nybble (?) 8 bits = 1 byte (B) 1024 bytes = 1 Kilobyte (KB) 1024 Kilobytes = 1 Megabyte (MB) 1024 Megabytes = 1 Gigabyte (GB) 1024 Gigabytes = 1 Terabyte (TB) Common prefixes: - kilo, meaning 1,000. (one thousand) 10^3 (Kilometer, 1,000 meters) - mega, meaning 1,000,000.

(one million) 10^6 (Megawatt, 1,000,000 watts) - giga, meaning 1,000,000,000 (one billion) 10^9 (Gigawatt, 1,000,000,000 watts) - tera, meaning 1,000,000,000,000 (one trillion) 10^12 The smallest amount of transfer is one bit. It holds the value of a 1, or a 0. (Binary coding). Eight of these 1's and zero's are called a byte. Why eight? The earliest computers could only send 8 bits at a time, it was only natural to start writing code in sets of 8 bits. This came to be called a byte. A bit is represented with a lowercase "b," whereas a byte is represented with an uppercase "b" (B). So Kb is kilobits, and KB is kilobytes. A kilobyte is eight times larger than a kilobit.

A simple 1 or 0, times eight of these 1's and 0's put together is a byte. The string of code: 10010101 is exactly one byte. So a small gif image, about 4 KB has about 4000 lines of 8 1's and 0's. Since there are 8 per line, that's over (4000 x 8) 32,000 1's and 0's just for a single gif image. How many bytes are in a kilobyte (KB)? One may think it's 1000 bytes, but its really 1024. Why is this so? It turns out that our early computer engineers, who dealt with the tiniest amounts of storage, noticed that 2^10 (1024) was very close to 10^3 (1000); so based on the prefix kilo, for 1000, they created the KB. (You may have heard of kilometers (Km) which is 1000 meters).

So in actuality, one KB is really 1024 bytes, not 1000. It's a small difference, but it adds up over a while. The MB, or megabyte, mega meaning one million. Seems logical that one mega (million) byte would be 1,000,000 (one million) bytes. It's not however. One megabyte is 1024 x 1024 bytes. 1024 kilobytes is called one Megabyte. So one kilobyte is actually 1024 bytes, and 1024 of those is (1024 x 1024) 1048576 bytes. In short, one Megabyte is really 1,048,576 bytes. There is a difference of about 48 KB, which is a decent amount. If you have a calculator, you will notice that there is actually a 47KB difference. There is a difference of 48,576 bytes, divided by 1024, and you get the amount of real kilobytes...

47.4375 All of this really comes into play when you deal with Gigabytes, or roughly one billion bytes. One real Gigabyte is actually 1024 bytes x 1024 bytes x 1024 bytes...1,073,741,824. However, most people like to simplify this by simply saying that one Gigabyte is only 1,000,000,000 (one billion) bytes; which makes sense because the prefix Giga means one billion. References Kilobytes Megabytes Gigabytes Kilobytes Megabytes Gigabytes < CS101 The size of information in the computer is measured in kilobytes, megabytes, gigabytes, and terabytes. In this section, we'll look at common sizes you would see in real life, and work some arithmetic. Any thinking person today should have a rough idea of what KB, MB and GB are.

Kilobyte or KB Kilobyte KB - about 1 thousand bytes As we know, 1 byte is one typed letter - see below for why the word "about" is required here A small email text is about 2 KB A 5 page paper might be 100 KB Text does not take a lot of bytes to store compared to images or video Math: if you have N bytes, that's N/1000 KB e.g. 23,000 bytes is about 23 KB One kilobyte (KB) is a collection of about 1000 bytes. A page of ordinary roman alphabetic text takes about 2 kilobytes to store (about one byte per letter). A typical short email would also take up just 1 or 2 kilobytes. Text is one of the most naturally compact types of data at about one byte required to store each letter. In non-roman alphabets, such as Kanji, the storage takes up 2 or 4 bytes per "letter" which is still pretty compact compared to audio and images.

Megabyte or MB Megabyte (MB) - about 1 million bytes aka about 1000 KB MP3 audio is about 1 megabyte per minute A high quality digital picture is about 2-5 megabytes Math: if you have N KB, that's N/1000 MB e.g. 45,400 KB is 45.4 MB One megabyte is about 1 million bytes (or about 1000 kilobytes). An MP3 audio file of a few minutes or a 10 million pixel image from a digital camera would typically take up few megabytes. The rule of thumb for MP3 audio is that 1 minute of audio takes up about 1 megabyte. Audio and image and video data typically stored in "compressed" form, MP3 being an example. We'll talk about how compression works later. A data CD disk stores about 700 MB. The audio on a CD is not compressed, which is why it takes so much more space than the MP3. The series of bits are represented as spiral path of tiny pits in the silver material in the disk.

Imagine that each pit is interpreted as a 0, and the lack of a pit is a 1 as the spiral sequence is read. Fun fact: the whole spiral on a CD is over 5km long. Math - You Try It 2,000,000 bytes is about how many MB? 23,000 KB is about how many MB? 500 KB is about how many MB? Show Solution 2 MB 23 MB 0.5 MB Gigabyte or GB Gigabyte GB = about a billion bytes aka about 1000 MB GB is a common unit for modern hardware e.g. 4000 MB = 4 GB An ordinary computer might have: -4 GB or RAM -256 GB of persistent storage A DVD disk has a capacity 4.7GB (single layer) -Figure 2 GB per hour of video (varies greatly) A flash drive might hold 32 GB A small hard drive might hold 750 GB Math: if you have N MB, that's N/1000 GB One gigabyte (GB) is about 1 billion bytes, or 1 thousand megabytes.

A computer might have 4 GB of RAM. A flash memory card used in a camera might store 16 GB. A DVD movie is roughly 4-8 GB. Math - You Try It How many GB is 4,000,000,000 bytes? Say you have many 5 MB .jpeg images. How many fit on a 16 GB flash drive? Show Solution 4 GB 5 MB per image means 200 images fit in 1 GB. 200 * 16 is 12,000 Terabyte or TB One terabyte (TB) is about 1000 gigabytes, or roughly 1 trillion bytes. You can buy 1 TB and 2 TB hard drives today, so we are just beginning the time when this term comes in to common use. Gigabyte used to be an exotic term too, until Moore's law made it common. Gigahertz - Speed, not Bytes One gigahertz is 1 billion cycles per second (a megahertz is a million cycles per second). Gigahertz is a measure of speed, very roughly the rate that at a CPU can do its simplest operation per second.

Gigahertz does not precisely tell you how quickly a CPU gets work done, but it is roughly correlated. Higher gigahertz CPUs also tend to be more expensive to produce and they use more power (and as a result give off more heat) .. a challenge for putting fast CPUs in small devices like phones. The ARM company is famous for producing chips that are very productive with minimal power and heat. Almost all cell phones currently use ARM CPUs. Kilobyte / Megabyte / Gigabyte Word Problems You should be comfortable doing simple arithmetic to figure MB / GB sizes, just as you should be able to do basic computations with second, miles, kilos and so forth. Basic plan: before adding measures X and Y, convert them to be in the same units. Word Problems Solution Alice has 600 MB of data. Bob has 2000 MB of data. Will it all fit on Alice's 4 GB thumb drive? show Yes it fits: 600 MB + 2000 MB is 2600 MB. 2600 MB is 2.6 GB, so it will fit on the 4 GB drive no problem.

Equivalently we could say that the 4 GB drive has space for 4000 MB. Alice has 100 small images, each of which is 500 KB. How much space do they take up overall in MB? show 100 times 500 KB is 50000 KB, which is 50 MB. Your ghost hunting group is recording the sound inside a haunted Stanford classroom for 20 hours as MP3 audio files. About how much data will that be, expressed in GB? show MP3 audio takes up about 1 MB per minute. 20 hours, 60 minutes/hour, 20 * 60 yields 1200 minutes. So that's about 1200 MB, which is 1.2 GB. Alternate Terminology: Kibibyte Mebibyte Gibibyte Tebibyte It's convenient within the computer to organize things in groups of powers of 2. For example, 210 is 1024, and so a program might group 1024 items together, as a sort of "round" number of things within the computer.

The term "kilobyte" above refers to this group size of 1024 things. However, people also group things by thousands -- 1 thousand or 1 million items. There's this problem with the word "megabyte" .. does it mean 1024 * 1024 bytes, i.e. 220 which is 1,048,576, or does it mean exactly 1 million, 1000 * 1000. It's just a 5% difference, but marketers tend to prefer the 1 million, interpretation, since it makes their hard drives etc. appear to hold a little bit more. Also, the difference grows larger and larger for the gigabyte and terabyte sizes. In an attempt to fix this, the terms "kibibyte" "mebibyte" "gibibyte" "tebibyte" have been introduced to specifically mean the 1024 based units (see wikipedia kibibyte article ). These terms do not seem to have caught on very strongly thus far.

If nothing else, remember that terms like "megabyte" have this little wiggle room in them between the 1024 and 1000 based meanings. We will never grade off for this distinction .. "about a million" will be our close-enough interpretation for "megabyte". The "error" at the megabyte level is about 5%. At the terabyte level the error is about 10%. Conversion Calculator Bit Byte Kilobyte Megabyte Gigabyte Terabyte Petabyte Exabyte Byte Converter - File Size Calculator Conversion Calculator Use this tool to convert file storage size from one unit of measurement to another. The results will return all possible conversion options (bits, bytes, kilobytes, megabytes, gigabytes, terabytes, petabytes, and exabytes). You are visitor 13,725,829 to this calculator. File size The basic unit used in computer data storage is called a bit (binary digit). Computers use these little bits, which are composed of ones and zeros, to do things and talk to other computers. All your files, for instance, are kept in the computer as binary files and translated into words and pictures by the software (which is also ones and zeros).

This two number system, is called a "binary number system" since it has only two numbers in it. The decimal number system in contrast has ten unique digits, zero through nine. But although computer data and file size is normally measured in binary code using the binary number system (counted by factors of two 1, 2, 4, 8, 16, 32, 64, etc), the prefixes for the multiples are based on the metric system! The nearest binary number to 1,000 is 2^10 or 1,024; thus 1,024 bytes was named a Kilobyte. So, although a metric "kilo" equals 1,000 (e.g. one kilogram = 1,000 grams), a binary "Kilo" equals 1,024 (e.g. one Kilobyte = 1,024 bytes). Not surprisingly, this has led to a great deal of confusion. In December 1998, the International Electrotechnical Commission (IEC) approved a new IEC International Standard.

Instead of using the metric prefixes for multiples in binary code, the new IEC standard invented specific prefixes for binary multiples made up of only the first two letters of the metric prefixes and adding the first two letters of the word "binary". Thus, for instance, instead of Kilobyte (KB) or Gigabyte (GB), the new terms would be kibibyte (KiB) or gibibyte (GiB). The new IEC International Standards, which are not commonly used yet, are included below. Here's a few more details to consider: Although data storage capacity is generally expressed in binary code, many hard drive manufacturers (and some newer BIOSs) use a decimal system to express capacity. For example, a 30 gigabyte drive is usually 30,000,000,000 bytes (decimal) not the 32,212,254,720 binary bytes you would expect. Another trivial point is that in the metric system the "k" or "kilo" prefix is always lowercase (i.e.

kilogram = kg not Kg) but since these binary uses for data storage capacity are not properly metric, it has become standard to use an uppercase "K" for the binary form. When used to describe Data Transfer Rate, bits/bytes are calculated as in the metric system Kilobits per second is usually shortened to kbps or Kbps. Although technically speaking, the term kilobit should have a lowercase initial letter, it has become common to capitalize it in abbreviation (e.g. "56 Kbps" or "56K"). The simple "K" might seem ambiguous but, in the context of data transfer, it can be assumed that the measurement is in bits rather than bytes unless indicated otherwise.
