Frequently asked questions
Why is a nautical mile different?
It is defined as exactly 1,852 m - one minute of latitude - which is why sea and air navigation use it.
Which nautical mile definition is used?
The international nautical mile of exactly 1,852 metres, which is the standard for sea and air navigation worldwide.
Why does surveying use different feet?
US survey feet differ from the international foot by about 2 ppm - irrelevant for daily work but meaningful across large land surveys, which is why both appear as separate units.
