The Nautical Mile is used for global navigation, equaling one minute of latitude (about 1.15 statute miles). Commercial airliners cruise at altitudes of 35,000-40,000 feet (about 6 nautical miles). Modern nautical charts still use this measurement, and international maritime law specifies territorial waters in nautical miles. The Kilometer (km) is used for longer distances like city-to-city travel (e.g., 50 km), marathon races (42.195 km), or highway spans (e.g., 100 km). It's also used in aviation and sports like cycling.
To convert between Nautical Mile (nmi) and Kilometer (km), use the following formulas:
1 Nautical Mile (nmi) = 1.852 Kilometer (km)
1 Kilometer (km) = 0.5399568034557235 Nautical Mile (nmi)
1 nmi = 1 * 1.852 km = 1.852 km
5 nmi = 5 * 1.852 km = 9.26 km
10 nmi = 10 * 1.852 km = 18.52 km
20 nmi = 20 * 1.852 km = 37.04 km
50 nmi = 50 * 1.852 km = 92.60000000000001 km
100 nmi = 100 * 1.852 km = 185.20000000000002 km
