How does the odometer work?

How do odometers calculate distance travelled? Today, most odometers work by recording wheel rotations. The distance travelled is then calculated by multiplying the number of wheel rotations by the tyre circumference. The circumference of a tyre (circle) is obtained by multiplying the tyre diameter by pi (3.1416).
