About the Length Converter

The Length Converter moves any distance between the metric and imperial systems and shows the answer in every supported unit at once. The conversions use the international definitions agreed in 1959, where one inch is exactly 25.4 millimetres and one mile is exactly 1,609.344 metres, so the results match the values printed in engineering handbooks rather than rounded rules of thumb.

Use it for the conversions that come up when shopping online (a 32 inch monitor is 81.3 cm wide), reading a recipe or a running plan (a 10 km race is 6.21 miles), following building plans drawn in another country, or checking a flight distance quoted in nautical miles. Everything is calculated in your browser, so it keeps working offline once the page has loaded.

How to use the Length Converter

  1. Type the length you want to convert into the amount box.
  2. Pick the unit you are converting from and the unit you want the answer in.
  3. Read the highlighted answer, or scan the table underneath for the same length in every other unit.

Frequently asked questions

How many centimetres are in an inch?

Exactly 2.54 centimetres. The inch has been defined as 25.4 millimetres since the international yard and pound agreement of 1959, so the conversion is exact rather than approximate.

How do I convert feet to metres in my head?

Multiply feet by 0.3 for a quick estimate, or divide by 3.28 for a closer figure. Six feet is 1.83 metres, and one metre is a little over three feet three inches.

Why is a nautical mile different from a mile?

A nautical mile is 1,852 metres, which corresponds to one minute of latitude. It is used in aviation and shipping because it maps directly onto navigation charts. A statute mile is 1,609.344 metres.

How precise are the results?

Values are calculated at full double precision and displayed with up to six decimal places, which is far more than enough for construction, sport, shipping or classroom use.
