Multiply metres by 100 to get centimetres.
3 m = 300 cm
How to convert metres to centimetres
The centimetre is one hundredth of a metre (10⁻² m). The metre is the SI base unit of length, defined since 1983 by fixing the speed of light at exactly 299 792 458 m/s.
Worked example — 3 m: 3 × 100 = 300 cm.

About metres and centimetres
Metre (m)
1 m = 100 cmDefinition. The SI base unit of length, defined since 1983 by fixing the speed of light at exactly 299 792 458 m/s
History and origin
The metre was defined in 1793 as one ten-millionth of the distance from the equator to the North Pole, later realised as a platinum bar. Since 1983 it has been defined by fixing the speed of light at exactly 299 792 458 metres per second, tying it to a constant of nature rather than an object.
Current use
The metre is the base unit of length across the metric world, used for everything from building plans to sports fields; the United States is the main country that still measures everyday length in feet and inches.

Centimetre (cm)
1 cm = 0.01 mDefinition. One hundredth of a metre (10⁻² m)
History and origin

Current use
Centimetres are the everyday metric unit for body height, paper and screen sizes, and clothing measurements.
