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.
3. To convert the other way, type into Metres and the centimetres are recalculated.
4. Press Copy results to copy both values with the page title, or Copy link to share this exact conversion.

This page converts only cm ⇄ m. Need a different unit? Use the general length converter, where you can choose any “from” and “to” unit.

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. Results are calculated at full precision and rounded only for display (up to eight decimal places, with very large or small values shown in scientific notation).

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.

What is a centimetre?

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

What is a metre?

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.

Common mistakes to avoid

Mixing the international foot (0.3048 m) with the old u.s. survey foot, confusing nautical and statute miles, and writing decimal feet such as 5.5 ft as “5 ft 5 in” (it is 5 ft 6 in).
