Centimeters to meters table

Converting the other way: meters to centimeters

centimeters = meters × 100. So 4 meters is back to 400 centimeters; one meter is 100 centimeters. See the meters to centimeters table.

Quick estimate in your head

For a rough answer, multiply by about 0.01: 400 × 0.01 ≈ 4 m, against the exact 4 m (0.0% out). Good enough to check that a calculated result is sensible.

Common mistakes

The usual slip is using the factor the wrong way round. A centimeter is smaller than a meter, so the number of meters must come out smaller than the number of centimeters. If your answer goes the other way, divide instead of multiplying.
