Centimetre to Metre Converter
Convert cm to meters instantly. Free cm to meters calculator with formula, examples and FAQs.
Quick answer
1 cm equals 0.01 meters. To convert cm to meters, multiply the cm value by 0.01 — so 10 cm = 0.1 meters. This factor is exact, and the reverse conversion (meters to cm) simply divides by 0.01 instead of multiplying.

What is cm to meters?
Centimetre and Metre both measure length, so converting cm to meters restates the same quantity in a different unit. Shoppers, crafters and students reach for this conversion regularly. The relationship is fixed and linear, which means one factor (meters = cm × 0.01) maps every cm value to its exact meters equivalent.
Real-world uses: why convert cm to meters?
Converting cm to meters bridges two ways of measuring the same thing. People do it most often when checking screen, paper and print sizes, and on the receiving side when reading athletics track and field measurements. Having the exact value — not a rough estimate — prevents costly mistakes in paperwork, purchases and planning.
- •Converting body measurements for clothing and fitness.
- •Checking screen, paper and print sizes.
- •Reading furniture dimensions for small spaces.
- •School and craft measurements.
- •Reading athletics track and field measurements.

How the cm to meters conversion is calculated
This is the same arithmetic that calculators and search engines use — no rounded shortcuts.
meters = cm × 0.01
- Both cm and meters are defined in terms of the same base unit, the metre.
- 1 cm = 0.01 metre, and 1 meters = 1 metre.
- Divide one definition by the other to get the conversion factor: 0.01 ÷ 1 = 0.01.
- So meters = cm × 0.01. Multiply any cm value by 0.01 to get the result in meters.
Precision: The conversion factor is exact by international definition, so the result is an exact rational number. We display it rounded to four decimal places (or four significant figures for very small values).
Example calculations
- •1 cm = 0.01 meters
- •10 cm = 0.1 meters
- •30 cm = 0.3 meters

Common mistakes to avoid
- •Reading the result the wrong way round. Confirm the answer is in meters, not cm, before you rely on it.
- •Truncating instead of rounding, which compounds error across larger cm values.
- •Mixing metric and imperial units midway through a multi-step conversion instead of converting to a single base unit first.
Common questions about length conversions
Is this length conversion exact?
Yes. Factors such as 1 inch = 25.4 mm and 1 mile = 1,609.344 m are exact by international agreement, so the only rounding is in how many decimals we display.
Why do my results differ slightly from another tool?
Almost always because the other tool rounds the factor (e.g. 0.62 instead of 0.621371) or rounds partway through. We keep full precision and round only the final value.
Metric or imperial — which should I use?
Use metric (m, cm, km) for science and most countries, and imperial (ft, in, miles) for US and UK everyday distances. This page bridges the two exactly.
Can I round the answer?
Yes. For everyday use one or two decimals is plenty; engineering and science may need more. Round only at the end to avoid cumulative error.
History of these units
History of the centimetre
metric
The centimetre — one-hundredth of a metre — is part of the metric system formalised after the French Revolution. It is the everyday unit for body measurements, stationery and small objects in most of the world.
History of the metre
metric (SI base unit)
The metre is the SI base unit of length. First defined in 1793 from the Earth's meridian, it is today defined by the distance light travels in a vacuum in 1/299,792,458 of a second.
