Centimeters to Feet

Convert centimeters to feet with the exact factor (1 cm = 0.0328084 ft), a quick reference table, and common height and length examples.

cm to ft formula

To convert centimeters (cm) to feet (ft), multiply by 0.0328084, because 1 foot = 30.48 cm and 1 cm = 1 / 30.48 ft.

Quick reference: cm to ft

Common values

1 cm = 0.033 ft

10 cm = 0.328 ft

30 cm = 0.984 ft

100 cm = 3.28 ft

150 cm = 4.92 ft

180 cm = 5.91 ft

Worked example

Convert 100 cm to feet:

100 cm × 0.0328084 = 3.28084 ft

So 100 cm is exactly 1 meter, or about 3.28 ft.

Why convert cm to ft?

Feet are used for height and room dimensions in the US, while centimeters are standard elsewhere. Converting between them lets you read international sizes on a US scale.

Disclaimer

Unit conversions on this site use internationally recognized, fixed conversion factors (for example, 1 inch = 2.54 cm, 1 pound = 0.45359237 kg, 1 °F = (°C × 9/5) + 32). They are provided for general, informational, and educational use. For applications where accuracy is critical — such as medical dosing, engineering, scientific research, trade, or legal compliance — always verify results against authoritative sources such as the U.S. National Institute of Standards and Technology (NIST) and the official International System of Units (SI) brochure, and follow any applicable local standards.

Exact Constants & Authoritative Sources

Common Pitfalls & How to Avoid Them

US survey foot is deprecated

The old US survey foot (0.304800609601 m) was retired in 2023 in favor of the international foot (0.3048 m). Modern conversions use the international foot; mixing them drifts over long distances.

Inches vs. centimetres for screens

Display and wheel sizes are often rounded to the nearest convenient number; a "27-inch" monitor is nominal, not a precise 68.58 cm panel.

A unit-conversion reference site has no manufacturer-specific or device calibration parameters, so "layered tuning" does not apply here. The only real error-handling is input validation: the converter rejects non-numeric, empty, or out-of-range entries and shows a clear message, then falls back to exact constants above. No estimated or rounded figures are ever presented as exact.
