About the feet to centimeters converter

To convert feet to centimeters, multiply by 30.48; to convert back, multiply by 0.032808399. For example, 6 ft is about 182.88 cm. Displayed factors and results may be rounded.

A distance stated in feet may describe ceiling height, lumber or a route segment. Combine separate feet and inches into the correct total before using a single-value conversion. The unit here is the international foot; historical survey documents may use a different definition.

International definition of foot: 1 ft = 12 in = 0.3048 m. These values are exact.

Both units are defined exactly. Calculations use 50 significant digits and round only for display.

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.

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.

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.

For the opposite direction, use cm to feet. The height converter rounds a height to whole inches and converts weight beside it. For meters, use feet to meters, and for square units the area converter.

Questions

How many centimeters are in one foot?

1 ft is about 30.48 cm. International definition of foot: 1 ft = 12 in = 0.3048 m. These values are exact.

How do I convert feet to centimeters?

Multiply by 30.48: 6 ft × 30.48 ≈ 182.88 cm. To convert back, divide by the same factor. The factor shown may be rounded.

How can I estimate feet in centimeters without a calculator?

Multiply by 30. This is 1.6% below the exact factor (about 30.48), so 6 ft comes out as 180 cm instead of 182.88 cm.
