Feet (ft) to Nautical miles (nmi) Conversion
Feet
The foot is a unit of length equal to exactly 0.3048 metres, defined by the international yard and pound agreement of 1959. Today it is the primary unit of height measurement in the United States and the United Kingdom, and is used in aviation worldwide to express altitude, where flight levels are defined in hundreds of feet. One foot equals 12 inches and one third of a yard.
Nautical miles
The nautical mile is a unit of length equal to exactly 1,852 metres, adopted internationally in 1929. Unlike most length units, it is geometrically derived: it corresponds to one arcminute (1/60 of a degree) of latitude, making it naturally suited to navigation on the spherical surface of the globe. Speed in nautical miles per hour is expressed in knots.
