Convert between metres, feet, miles, inches, and more.
Free to use, no sign-up required. Length Converter is one of 198 tools built into Xenition, alongside a chat that can use them for you.
Converts a length or distance between metric units (mm, cm, m, km), imperial and US units (in, ft, yd, mi) and the nautical mile. People reach for it with a height in feet and inches, a race distance, or a sea chart.
Every unit is stored in metres and the value is scaled through metres. The inch is exactly 0.0254 m and the mile exactly 1,609.344 m by international definition, and the nautical mile is 1,852 m.
A height of 5 ft 10 in is 70 in. Enter 70, choose in → cm, and you get 177.8 cm. A marathon, 42.195 km, comes out as 26.218757 mi.
The tool takes one unit at a time, so turn the height into inches first: feet × 12 + inches. 6 ft 2 in is 74 in, which you can then convert to cm or m.
A statute mile is 1,609.344 m and is used on roads in the US and UK. A nautical mile is 1,852 m, based on one minute of latitude, and is used at sea and in aviation. Knots are nautical miles per hour.
Length Converter converts between 9 units: mm, cm, in, ft, yd, m, km, mi and nautical mi. Factors are given against m.
| Unit | In m | 1 m equals |
|---|---|---|
| 1 mm | 0.001 m | 1000 mm |
| 1 cm | 0.01 m | 100 cm |
| 1 in | 0.0254 m | 39.3700787402 in |
| 1 ft | 0.3048 m | 3.280839895 ft |
| 1 yd | 0.9144 m | 1.0936132983 yd |
| 1 km | 1000 m | 0.001 km |
| 1 mi | 1609.344 m | 0.0006213712 mi |
| 1 nautical mi | 1852 m | 0.0005399568 nautical mi |
Common quantities in m, converted. Every value is computed from the factors above, so the chart and the converter cannot disagree.

1 m is 1000 mm. To convert m to mm, divide by 0.001 — so 10 m is 10000 mm.
1 mm is 0.001 m. To convert mm to m, multiply by 0.001 — so 10 mm is 0.01 m.
1 m is 100 cm. To convert m to cm, divide by 0.01 — so 10 m is 1000 cm.
1 cm is 0.01 m. To convert cm to m, multiply by 0.01 — so 10 cm is 0.1 m.
1 m is 39.3700787402 in. To convert m to in, divide by 0.0254 — so 10 m is 393.7007874016 in.
1 in is 0.0254 m. To convert in to m, multiply by 0.0254 — so 10 in is 0.254 m.
1 m is 3.280839895 ft. To convert m to ft, divide by 0.3048 — so 10 m is 32.8083989501 ft.
1 ft is 0.3048 m. To convert ft to m, multiply by 0.3048 — so 10 ft is 3.048 m.
You do not have to open Length Converter to use it. Ask Xenition in plain language and it runs the right tool, then carries the answer into whatever you are working on — a document, a spreadsheet, a deck.
