Feet to Centimeters Converter

Feet to Centimeters

Convert feet (ft) to centimeters (cm). Both measure distance and dimension, and the conversion comes up in construction, navigation, sports work.

The Formula

`` centimeters = feet × 30.48 feet = centimeters × 0.0328083989501 `

One foot is 30.48 centimeters, and one centimeter is 0.032808 feet.

What Each Unit Is

Feet (ft) — exactly 0.3048 metres, or one third of a yard. A human foot, standardised across centuries of conflicting local definitions.

Centimeters (cm) — one hundredth of a metre. A metric subdivision, and the everyday unit for body and object measurements in metric countries.

A Sense of Scale

• A ceiling is 8–9 ft
• Aviation altitude is always in feet
• A door is about 6.7 ft
• A fingernail is about 1 cm wide
• A credit card is 8.6 cm long
• A4 paper is 21 cm wide

Doing It in Your Head

Multiply by 30. That is off by 1.57% — close enough to judge a distance, a weight or a price, and not close enough to sign off on a drawing.

Precision

The factor 30.48 is rounded. For engineering work carry more digits than the table above, and round only at the end — rounding at each step compounds.

In Code

`javascript const footToCentimeter = (value) => value * 30.48; ``

How Many Decimals Do You Need?

Rounding the factor costs accuracy, and how much depends on the factor. Converting 137 ft with the factor truncated at each decimal place:

Decimals kept	Factor	137 ft becomes	Error
0	30	4,110	1.5748%
1	30.5	4,178.5	0.0656%
2	30.48	4,175.76	—
3	30.48	4,175.76	—
4	30.48	4,175.76	—

A rule that holds for any conversion: round once, at the end. Rounding the factor and then multiplying compounds the error through every subsequent calculation, while carrying full precision and rounding the final answer does not.

The right number of significant figures is set by your input, not by the converter. If you measured feet to three significant figures, the answer in centimeters is only good to three — writing more digits claims precision the measurement never had.
