Convert a flight or route distance from kilometers to miles and nautical miles.

About Kilometers to Miles

Multiplying kilometers by 0.621371 gives statute miles, while 0.539957 converts to nautical miles, the standard unit in aviation. Feet is a further scale for ground reference. Aircraft and charts commonly use nautical miles, so converting trip distances into the right unit avoids misreading flight plans and range figures.
