Meters to Centimeters Converter

Meters to Centimeters

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

The Formula

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

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

50 m	5,000 cm
100 m	10,000 cm
500 m	50,000 cm
1,000 m	100,000 cm

The Other Direction

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

What Each Unit Is

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.

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

A Sense of Scale

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

Precision

The factor 100 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 meterToCentimeter = (value) => value * 100; ``

How Many Decimals Do You Need?

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

Decimals kept	Factor	137 m becomes	Error
0	100	13,700	—
1	100	13,700	—
2	100	13,700	—
3	100	13,700	—
4	100	13,700	—

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 meters to three significant figures, the answer in centimeters is only good to three — writing more digits claims precision the measurement never had.
