Subject: Unit converters

A centimeter measurement often comes from a tape used for furniture, clothing or body height. Keep the full reading, including a decimal part, when comparing it with a specification written in another unit. A decimal length is different from a feet-and-inches notation.

One centimetre is about 0.032808399 feet, so 180 cm is 5.905512 ft. To convert cm to feet, multiply by 0.032808399; to convert back, multiply by 30.48.

The centimetre is one hundredth of a metre, the SI base unit of length. The factor has no exact decimal form, so results are computed with 50 significant digits and rounded only for display.

## Inputs

- **Centimeters (cm)**

## Results

- Feet (ft) — main result

## Questions

### When would I convert cm to feet?

A centimeter measurement often comes from a tape used for furniture, clothing or body height. Keep the full reading, including a decimal part, when comparing it with a specification written in another unit. A decimal length is different from a feet-and-inches notation.

### How many feet are in a centimetre?

One centimetre is about 0.032808399 feet. The centimetre is one hundredth of a metre, the SI base unit of length.

### How do you convert cm to feet?

Multiply the number of centimeters by 0.032808399. For example, 180 cm × 0.032808399 = 5.905512 ft. To go the other way, divide by 0.032808399.

### How can I estimate cm to feet without a calculator?

Multiply by 0.033. That is 0.6% high of the exact factor 0.032808399, so 180 cm comes out as 5.94 ft instead of 5.9055.

### How accurate is the centimeters to feet converter?

Accuracy depends on your inputs and the method's assumptions. Decimal arithmetic uses 50 significant digits, but estimates, numerical methods and source data can be less precise; the displayed rounding does not remove those limits. It is checked against 3 worked examples whose answers come from independent sources; for example, “180 cm to ft” is checked against Exact-fraction computation from the legal unit definitions (scripts/gen-pairs.py, Python fractions).
