Kilo ( from the Greek χίλιοι, literally a thousand ) is a decimal unit prefix in the metric system denoting multiplication by one thousand ( 10 ). It is used in the International System of Units where it has the unit symbol k, in lower case. The prefix kilo is derived from the Greek word χίλιοι ( chilioi ), meaning `` thousand ''. It was originally adopted by Antoine Lavoisier 's research group in 1795, and introduced into the metric system in France with its establishment in 1799. In 19th century English it was sometimes spelled chilio, in line with a puristic opinion by Thomas Young Contents 1 Examples 2 kilobyte 3 Exponentiation 4 See also 5 References Examples one kiloliter is 1000 litres one kilogram is 1000 grams one kilometre is 1000 metres one kilojoule is 1000 joules one kilobaud is 1000 baud one kilohertz is 1000 hertz one kilobit is 1000 bits one kilobyte ( kB ) is 1000 bytes one kΩ is 1000 ohms Kilobyte For the kilobyte, a second definition has been in common use in some fields of computer science and information technology. It uses kilobyte to mean 2 bytes ( = 1024 bytes ), because of the mathematical coincidence that 2 is approximately 10. The reason for this application is that digital hardware and architectures natively use base 2 exponentiation, and not decimal systems. JEDEC memory standards still permit this definition, but acknowledge the correct SI usage. NIST comments on the confusion caused by these contrasting definitions : `` Faced with this reality, the IEEE Standards Board decided that IEEE standards will use the conventional, internationally adopted, definitions of the SI prefixes '', instead of kilo for 1024. To address this conflict, a new set of binary prefixes has been introduced, which is based on powers of 2. Therefore, 1024 bytes are defined as one kibibyte ( 1 KiB ). Exponentiation When units occur in exponentiation, such as in square and cubic forms, any multiplier prefix is considered part of the unit, and thus included in the exponentiation. 1 km means one square kilometre or the area of a square that measures 1000 m on each side or 10 m ( as opposed to 1000 square meters, which is the area of a square that measures 31.6 m on each side ). 1 km means one cubic kilometre or the volume of a cube that measures 1000 m on each side or 10 m ( as opposed to 1000 cubic meters, which is the volume of a cube that measures 10 m on each side ).
