Distance conversion chart

Now, we are going to explain how to quickly convert different units from the same system, check out the following distance conversion pictures:

  1. Metric measurement system
length conversion chart - metric system. Km to m to cm to mm.

As an example:

  • 6 km = 6 * 1000 = 6000 m
  • 180 cm = 180 / 100 = 1.8 m
  1. Imperial / US measurement system
length conversion chart - imperial system. Mi to yd to ft to in.

For instance:

  • 5 yd = 5 * 3 = 15 ft
  • 144 in = 144 / 12 = 12 ft

You can verify them all in our distance converter calculator.

Inch and meter definition

ruler with centimeters and inches

An inch is equal to 2.54 centimeters.

1 in = 2.54 cm

One inch is also equal to 1⁄36 yard, 1⁄12 of a foot or 1⁄63360 of a mile. Check it in our distance conversion calculator.

On the other hand, the meter definition changed as scientific methods in measuring developed. Now it's defined as the distance of the path traveled by light in a vacuum in 1/299,792,458 of a second.
