Background
Imperial and US units are defined exactly in terms of the meter: 1 inch = 0.0254 m, 1 foot = 0.3048 m, 1 yard = 0.9144 m, 1 mile = 1,609.344 m and 1 nautical mile = 1,852 m. Conversions go through meters.
The nautical mile is based on one minute of latitude and is used at sea and in aviation.
Common mistakes
- Entering feet and inches as a single decimal. 5.10 ft is not 5 ft 10 in. Convert to inches first.
- Confusing the statute mile with the nautical mile.
- Rounding too early when chaining several conversions.
