In this video we will be going over how to measure the width of different objects using a caliper. First let's go over some of the different parts of the caliper. These are the jaws of the caliper. The object that you want to measure gets placed in between these. On the shaft of the caliper you will see a ruler. The number is on the ruler represents centimeters while each tick in between represents one tenth of a centimeter or one millimeter. You'll notice that as I move the jaws around on the caliper but the needle on the dial moves as well. The number is on the style represent tenths of the millimeter on the ruler while the ticks in between these numbers represents 0.02 millimeters. As you can see written on this style. Now let's begin taking measurements with our caliper. Before we begin we will need to make sure that the dial on the caliper is zero properly. Close the jaws on the caliper all the way. If the needle does not line up with the zero you will need to turn the dial so that the needle lines up. Now that our caliper is caliper properly we can begin taking our measurement. Open up the jaws of the caliper and place the object that you want to measure in between. For this example we will be measuring the width of this red wire. Place the object in between and close the jaws all the way. Secure the jaws into place, twist the screw behind the dial. Now let's look at our measurement. You'll see on the ruler that the jaws right after the third tick. So we have three millimeters and on the dial the needle lands right on top of 0.4. So our measurement of the width of this wire is 3.4 millimeters. Let's do another example. Here we will be measuring the width of this pencil. Open up the jaws of the caliper. Place the object that you want to measure in between. Close the jaws of the caliper all the way and secure it using the screw. Now let's take a look at our measurement. You'll see on the caliper that the jaws right after the seventh tick. So we have seven millimeters and the needle is right in between the second and first tick after the zero. So we have 7.0.02 plus 0.01 millimeters since we're halfway in between. So our measurement is 7.03 millimeters.
