# cm to m Converter URL: https://speedycalculator.com/calculators/conversion/cm-to-m/ Last updated: 2026-10-25 > Convert centimetres (cm) to metres (m): 1 centimetre = 0.01 m, so multiply by 0.01 or divide by 100. Both fields are editable, so you can also type in metres and get centimetres back. ## Inputs - Centimetres (cm) ## Results - Metres ## Formula ``` 1 cm = 0.01 m 1 m = 100 cm m = cm × 0.01 ``` ## Explanation 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 - Type the number of centimetres into the **Centimetres** field. Decimals such as 87.5 are fine. - Read the answer in **Metres** – it updates as you type, with no button to press. - To convert the other way, type into **Metres** and the centimetres are recalculated. - 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 - Write down the value in centimetres, for example **175 cm**. - Multiply by the conversion factor 0.01 (because 1 centimetre = 0.01 m). - 175 × 0.01 = **1.75 m**. - To go back from metres to centimetres, divide by 0.01 – or multiply by 100. ### cm to m conversion table CentimetresMetresMetresCentimetres1 cm0.01 m1 m100 cm5 cm0.05 m2 m200 cm10 cm0.1 m5 m500 cm50 cm0.5 m10 m1,000 cm75 cm0.75 m20 m2,000 cm100 cm1 m50 m5,000 cm150 cm1.5 m100 m10,000 cm160 cm1.6 m1,000 m100,000 cm170 cm1.7 m180 cm1.8 m200 cm2 m500 cm5 m ### 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). ## Worked example Inputs — Centimetres: 175 cm. Results — **Metres = 1.75 m**. ## FAQ **How many metres is 150 cm?** 1.5 m. **How many cm in a metre?** 100. **How do I convert centimetres to metres?** Multiply the number of centimetres by 0.01. For example, 175 cm × 0.01 = 1.75 m. **How do I convert metres back to centimetres?** Divide by 0.01 (or multiply by 100), or simply type the value into the metres field above. **What is 10 cm in metres?** 10 cm = 0.1 m. **What is 100 cm in metres?** 100 cm = 1 m. **Is this conversion exact?** Yes. The factor comes from the official definitions of both units (NIST and the SI), so the only difference you may see is rounding in the last displayed digit. **Can I convert to other units on this page?** This page converts only between centimetres and metres. To pick any length unit, use the general length converter linked under Related calculators. **What formula does the cm to m Converter use?** 1 cm = 0.01 m. ## Sources - [NIST Special Publication 811 – Guide for the Use of the International System of Units](https://www.nist.gov/pml/special-publication-811) - [NIST Handbook 44 Appendix C – General tables of units of measurement](https://www.nist.gov/pml/owm/nist-handbook-44-current-edition)
