Frequently Asked Questions

How many centimetres are in an inch?

Exactly 2.54. That value is a definition rather than a measurement, agreed internationally in 1959, which is why every other imperial length converts exactly.

How do I convert my height?

Use the feet-and-inches mode. It takes two fields and returns centimetres, so 5 ft 9 in gives 175.26 cm without you having to convert the inches separately.

What is a nautical mile?

Exactly 1,852 metres, originally one minute of latitude. It is used in marine and air navigation because it maps directly onto charts, and speed in nautical miles per hour is a knot.
