Centimeters to Meters Converter

Centimeters to Meters

Convert centimeters (cm) to meters (m). Both measure distance and dimension, and the conversion comes up in construction, navigation, sports work.

The Formula

`` meters = centimeters × 0.01 centimeters = meters × 100 `

One centimeter is 0.01 meters, and one meter is 100 centimeters.

Conversion Table

Centimeters	Meters
1 cm	0.01 m
2 cm	0.02 m
5 cm	0.05 m
10 cm	0.1 m
25 cm	0.25 m
50 cm	0.5 m
100 cm	1 m
500 cm	5 m
1,000 cm	10 m

The Other Direction

Meters	Centimeters
1 m	100 cm
2 m	200 cm
5 m	500 cm
10 m	1,000 cm
25 m	2,500 cm
50 m	5,000 cm
100 m	10,000 cm
500 m	50,000 cm
1,000 m	100,000 cm

What Each Unit Is

Centimeters (cm) — one hundredth of a metre. A metric subdivision, and the everyday unit for body and object measurements in metric countries.

Meters (m) — the distance light travels in a vacuum in 1/299,792,458 of a second — the SI base unit of length. Defined in 1793 as one ten-millionth of the distance from the equator to the North Pole, then by a platinum bar, and since 1983 by the speed of light.

A Sense of Scale

• A fingernail is about 1 cm wide
• A credit card is 8.6 cm long
• A4 paper is 21 cm wide
• A doorway is about 2 m tall
• An Olympic pool is 50 m
• A city block is 80–120 m

Precision

The factor 0.01 is exact by international agreement, not a rounded approximation. Any imprecision in a result comes from your input, not the conversion.

In Code

`javascript const centimeterToMeter = (value) => value * 0.01; ``

How Many Decimals Do You Need?

Rounding the factor costs accuracy, and how much depends on the factor. Converting 137 cm with the factor truncated at each decimal place:

Decimals kept	Factor	137 cm becomes	Error
0	0	0	100.0000%
1	0	0	100.0000%
2	0.01	1.37	—
3	0.01	1.37	—
4	0.01	1.37	—

A rule that holds for any conversion: round once, at the end. Rounding the factor and then multiplying compounds the error through every subsequent calculation, while carrying full precision and rounding the final answer does not.

The right number of significant figures is set by your input, not by the converter. If you measured centimeters to three significant figures, the answer in meters is only good to three — writing more digits claims precision the measurement never had.
