Feet to centimeters converter

How to convert feet to centimeters

Multiply feet by 30.48. One foot is exactly 30.48 cm, so 5 ft = 152.4 cm, 6 ft = 182.88 cm and 2 ft = 60.96 cm. For a height in feet and inches, add 2.54 cm for each extra inch: 5 ft 10 in = 152.4 + 25.4 = 177.8 cm.

The factor comes from the international foot of exactly 0.3048 m in NIST's conversion tables, with 100 cm in a meter. To check a result, divide it by 30.48: 177.8 ÷ 30.48 = 5.8333 ft, which is 5 ft 10 in.

These rows are decimal feet: 5.10 means 5.1 feet, not 5 feet 10 inches.

The same factor covers any length: 100 ft is 3,048 cm.

Feet and inches to centimeters

Use cm = feet × 30.48 + inches × 2.54. For 5 ft 7 in: 152.4 + 17.78 = 170.18 cm.

Just below the chart, 5 ft 2 in is 157.48 cm.

When 5.10 means 5 feet 10 inches

A height is sometimes written 5.10 or 510 to mean 5 ft 10 in. Converted as numbers, those are very different lengths:

• 5.10 ft is 155.448 cm, while 5 ft 10 in is 177.8 cm.
• 5.11 ft is 155.7528 cm, while 5 ft 11 in is 180.34 cm.
• 510 ft is 15,544.8 cm, more than 155 meters.

Decimal 5.5 ft is 5 ft 6 in, or 167.64 cm, because half a foot is six inches. Someone who writes 5.5 for 5 ft 5 in means 165.1 cm, so rewrite any such height with units before converting it.

Areas and tolerances

Square feet need the factor squared, 30.48² = 929.0304. A 3 ft × 5 ft rug covers 15 ft², which is 13,935.456 cm².

A tolerance converts like any length: ±0.01 ft is ±0.3048 cm.

Typing feet and inches

• Typed as feet, 5+10/12 means 5 ft 10 in and gives 177.8 cm.
• The length converter accepts 5 ft 10 in written with units.
