Centimeters to Feet Converter

Centimeters to Feet

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

The Formula

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

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

What Each Unit Is

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

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

A Sense of Scale

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

Precision

The factor 0.0328083989501 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 centimeterToFoot = (value) => value * 0.0328083989501; ``

How Many Decimals Do You Need?

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

Decimals kept	Factor	137 cm becomes	Error
0	0	0	100.0000%
1	0	0	100.0000%
2	0.03	4.11	8.5600%
3	0.033	4.521	0.5840%
4	0.0328	4.4936	0.0256%

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 centimeters to three significant figures, the answer in feet is only good to three — writing more digits claims precision the measurement never had.

Other Conversions From Centimeters

The same value in every other unit this converter supports for length:

From	To	Unit
1 cm	0.01 m	Meters
1 cm	1.0000e-5 km	Kilometers
1 cm	10 mm	Millimeters
1 cm	6.2137e-6 mi	Miles
1 cm	0.0109361 yd	Yards
1 cm	0.393701 in	Inches

Chaining conversions works — centimeters to metres to feet gives the same answer as centimeters to feet — but each step rounds, so a chain of three conversions carries three roundings. Convert directly where a direct factor exists.
