About Length Converter
Converts a length between metric units (millimetres, centimetres, metres, kilometres) and imperial ones (inches, feet, yards, miles), plus nautical miles for sea and air navigation. Every unit is shown at once from a single value.
The imperial units are defined exactly in terms of the metre — an inch has been exactly 25.4 mm since 1959 — so these conversions are exact definitions, not measurements, and the results are as precise as the number you type.
Where it helps
- Metric, imperial and nautical units side by side from one value.
- Uses the exact legal definitions, so there is no drift between units.
- Handles anything from fractions of a millimetre to thousands of kilometres.
- Groups large numbers with separators so they can be read at a glance.
Limits
- Feet and inches are shown as separate decimal values, not as a combined 5 ft 11 in.
- US survey feet, which differ from international feet by two parts in a million, are not included.
- Astronomical and atomic scales such as light years and ångströms are left out.
Frequently asked questions
How many centimetres are in an inch?
Exactly 2.54. The inch has been defined as 25.4 millimetres since the international yard and pound agreement of 1959.
How far is a mile in kilometres?
1.609344 km exactly. A kilometre is about 0.62 miles, so a 5 km run is a little over three miles.
What is a nautical mile?
1,852 metres, originally one minute of latitude. Ships and aircraft use it together with knots, which are nautical miles per hour.
