# Different types of measurement

There are **3** different ways to measure with calipers.

1.Measuring the external dimension of a part. To do this clamp on the outside using the external measuring jaws.

EX: Measuring the side lengths of a cube.

3.Measuring the depth of a part. To do this use the depth gauge at the end of the calipers.

EX: Measuring to the bottom of a threaded hole to pick out the right sized bolt.
