Questions people ask
How many centimetres are in an inch?
Exactly 2.54. The inch has been defined against the metre since 1959, so this is a definition rather than a measurement.
How do I convert my height to feet and inches?
Convert to inches first, then divide by 12: the whole number is feet and the remainder is inches. 175 cm is 68.9 in, or 5 ft 8.9 in.
What is a nautical mile?
1,852 metres — roughly one minute of latitude. It is used in shipping and aviation, and is about 15% longer than a land mile.
