What each Length input means

Value
The length to convert, decimals allowed. For a height in feet and inches, enter decimal feet — 5 ft 9 in is 5.75 ft — or convert the inches on their own.
From
The unit you have. Millimetres, centimetres, metres and kilometres step by powers of ten; inches, feet, yards and miles are tied to them exactly, an inch being 2.54 cm.
To
The unit you want. The table under the answer gives the same length in every unit on the page.

Length conversion formula

result = value × (metres in one 'from' unit ÷ metres in one 'to' unit)

xto=xfrom×ffromftox_{\text{to}} = x_{\text{from}} \times \frac{f_{\text{from}}}{f_{\text{to}}}

Every length here is pinned to the metre. Since the international yard and pound agreement of 1959 the inch has been exactly 25.4 mm, which makes the foot exactly 0.3048 m, the yard 0.9144 m and the mile 1,609.344 m; the nautical mile is defined as 1,852 m. To convert, take the metres in one of the unit you have, divide by the metres in one of the unit you want, and multiply your number by that factor — so feet to inches is 0.3048 ÷ 0.0254 = 12. The page shows that factor, the multiplication, and your value in every other unit at once.

Length conversion worked example

5 feet × 0.3048 = 1.524 metres, exactly — the foot has been defined as 0.3048 m since 1959. Going the other way, a height of 1.8 m is 1.8 ÷ 0.3048 = 5.906 ft, or 5 ft 10.9 in once the 0.906 ft is multiplied by 12.

More Length examples

A 10K race: 10 km × 0.621371 = 6.213712 mi, the '6.2 miles' runners quote.

A 30-inch inseam: 30 × 2.54 = 76.2 cm, exactly, because the inch is defined as 2.54 cm.

An American football field's 100 yards between the goal lines: 100 × 0.9144 = 91.44 m.

Where the Length converter can give the wrong answer

  • The US survey foot (1200/3937 m) differs from the international foot by 2 parts per million; it matters only for land surveys and was retired by NIST at the end of 2022.
  • Feet-and-inches heights need two steps: convert to decimal feet, then multiply the fraction by 12 for inches.
  • The display rounds to six decimal places; the factors themselves are exact.
  • Area and volume are not lengths: a square foot is 0.3048² m², not 0.3048. Use the area or volume converter.
