About Feet → Cm
Feet and inches dominate US height and construction measures, while centimeters are standard in metric countries and medical records abroad. Converting feet to centimeters clarifies international product specs and travel documents.
One foot equals 30.48 centimeters exactly by definition, with inches contributing additional precision when you enter them separately.
Use this directional converter when you know an imperial height or length and need metric output—not the reverse direction.
How to use this tool
Enter feet and optional inches. Calculate to see total length in centimeters.
Formula & methodology
This feet to cm converter applies the standard relationship below. Intermediate values are kept at full precision; only the displayed result is rounded.
cm = (feet x 12 + inches) x 2.54
Worked example
To convert 5 ft 10 in: total inches = 5 × 12 + 10 = 70 in. Multiply by 2.54: 70 × 2.54 = 177.8 cm (1.778 m). Because 2.54 is an exact definition, this result is exact, not an approximation.
Tips for accurate results
For human height, add inches rather than rounding feet only.
2.54 cm per inch is exact—avoid using 2.5 for final answers.
Reverse conversion? Use the cm-to-feet tool for cm to ft/in.
Markings on tapes may show both units—verify which you are reading.
