cm to m Converter

There are 100 centimetres in a metre: move the decimal point two places left. 175 cm is 1.75 m.

How to use the cm to m Converter

1. Type the number of centimetres into the Centimetres field. Decimals such as 87.5 are fine.
2. Read the answer in Metres. It updates as you type, with no button to press. The same amount is also shown in mm, ft, in.
3. To go from metres back to centimetres, type into the Metres field instead. Every field also has a unit menu with all 27 length units, for example km, mm, dm, µm, nm, Å, in, ft, yd, mi, nmi, mil, furlong.

How it works

Both units measure length, so they are always in the same ratio: one centimetre equals 0.01 metres. The calculator multiplies the number of centimetres you type by 0.01 to give metres, and when you type into the metres field it divides by the same factor to give centimetres. Because the ratio never changes, doubling the centimetres always doubles the metres, for example 350 cm is 3.5 m.

How to convert centimetres to metres

1. Write down the value in centimetres, for example 175 cm.
2. Multiply by the conversion factor 0.01 (because 1 centimetre = 0.01 m).
3. 175 × 0.01 = 1.75 m.
4. To go back from metres to centimetres, divide by 0.01, or multiply by 100.

Length units explained

Centimetre (cm)

A centimetre is one hundredth of a metre (10 mm). It is the everyday metric unit for body height, clothing, furniture and school rulers.

Metre (m)

The metre is the SI base unit of length. Since 1983 it has been defined as the distance light travels in a vacuum in 1/299,792,458 of a second, which ties it to a fundamental constant rather than a physical bar of metal.
