Rounding and precision rules
- Convr calculates first and rounds the displayed result only once, at the final step.
- The default is a maximum of 6 decimal places; trailing zeros are removed.
- Very small values that would appear as zero, and values of 10¹² or more, use scientific notation.
- Display precision is not measurement uncertainty. For scientific, engineering, or regulated work, retain only the digits justified by the source measurement.
Practical context
Understanding this conversion
Feet appear in building plans, room sizes, human height, aviation, and US product specifications. Centimeters offer a convenient metric result for dimensions that do not need a full meter.
The international foot is defined exactly from the meter, so 30.48 centimeters per foot is an exact relationship rather than a measured approximation.

Calculation
Foot to Centimeter formula
cm = ft × 30.48
Calculations retain full precision and the result is rounded only for display.
Worked example
For 10 ft, the result is 304.8 cm. Substitute 10 ft into the formula to obtain 304.8 cm.
A numerical value expressed in centimeter is usually larger than the same measurement expressed in foot, because 1 ft equals 30.48 cm.
