Frequently asked questions

How many centimeters are in a meter?

How do I convert centimeters back to meters?

Divide instead of multiplying, or equivalently multiply by 0.01. One centimeter is 0.01 meters.

Is this conversion exact?

Yes. Since the international agreement of 1959, the relationship between meters and centimeters is defined exactly rather than measured, so the only rounding here is in how many decimal places we show.

Where is each of these units used?

Meters: the SI base unit of length, defined by the distance light travels in 1/299,792,458 of a second. Centimeters: how height and clothing sizes are quoted almost everywhere outside the US.
