How it works
Every unit is converted through metres using exact definitions: 1 inch is exactly 2.54 cm, 1 foot is 0.3048 m, 1 mile is 1,609.344 m and 1 nautical mile is 1,852 m.
These definitions come from the International Yard and Pound Agreement of 1959 and the international definition of the nautical mile.
