What is the difference between Statute vs Nautical Miles?
On the ocean, distances are calculated slightly different than on land, hence Nautical phrases are applied as opposed to land or Statute terminology.
Nautical Mile (nmi): A unit of distance used in navigation and based on the length of one minute of arc taken along a great circle. This is also sometimes referred to as the International Nautical Mile or an International Air Mile. The value 1,852 meters (6076.1 ft) has been adopted internationally.
Statute mile: A unit of distance equal to 1,609 km (0.869 nmi, 5,280 ft.).
1 nautical mile = 1.15 statute miles
1 statute mile = 1.6 kilometers
A knot is a unit of speed one nautical mile per hour, which is approximately 1.15 statute miles per hour.
