How it works

Each of the 27 length units on this page is defined by a factor relative to the metre, the base unit: 1 ft = 0.3048 m and 1 in = 0.0254 m, for example. The calculator first turns the value you type into metres, then turns that into the unit you picked in the “To” menu and into yards, miles and metres. Typing into any result works backwards the same way, so the feet and inches values always describe the same amount.

How to convert length units

1. Choose the unit you have in the From menu and type the value, for example 1 ft.
2. Choose the unit you want in the To menu, for example inches. The page heading changes to “Feet to Inches Converter”.
3. The calculator multiplies by the metre factor of the “from” unit and divides by the factor of the “to” unit: 1 ft × 0.3048 ÷ 0.0254 = 12 in.

Length units explained

Foot (ft)

The international foot is exactly 0.3048 m and contains 12 inches. It remains the everyday unit for height, room dimensions and altitude in the U.S., and for aviation altitude worldwide.

Inch (in)

The inch has been defined as exactly 25.4 mm since 1959. It is used in the U.S. for almost everything and worldwide for screen sizes, wheel and tyre sizes, pipe threads and many tools.

Yard (yd)

The yard is 3 feet (36 inches), exactly 0.9144 m. It is used for fabric, American and Canadian football fields, golf distances and, as the gaj, for land in South Asia.

Mile (mi)

The statute mile is 5,280 feet, exactly 1,609.344 m. U.S. and UK road signs, speed limits and running races such as the mile and the marathon (26.2 mi) use it.

Metre (m)

The metre is the SI base unit of length. Since 1983 it has been defined as the distance light travels in a vacuum in 1/299,792,458 of a second, which ties it to a fundamental constant rather than a physical bar of metal.

Centimetre (cm)

A centimetre is one hundredth of a metre (10 mm). It is the everyday metric unit for body height, clothing, furniture and school rulers.

Millimetre (mm)

A millimetre is one thousandth of a metre. Engineering drawings, construction plans, rainfall, screws, bolts and jewellery are all dimensioned in millimetres.

Kilometre (km)

A kilometre is 1,000 metres. It is the standard unit for road distances, maps, running races and travel in almost every country except the U.S. and UK, where miles are still used on road signs.
