What is Nautical Miles per Hour?
Nautical Miles per Hour (nmi/h) is a unit of speed. A nautical mile per hour, or knot, equals exactly 1.852 kilometers per hour. It is a unit of speed commonly used in maritime and aviation navigation. The knot is internationally recognized by the International Hydrographic Organization and ICAO [bipm-si-brochure]. The knot originated from nautical practices using a rope with knots spaced at intervals to measure ship speed. It was standardized internationally in the mid-20th century to align with the nautical mile, defined as one minute of latitude [bipm-si-brochure]. Knots are standard in global maritime and aviation sectors, including the US Coast Guard, International Maritime Organization, and commercial airlines. It is the official speed unit for vessels and aircraft worldwide [nist-si-guide].
What is Miles per Hour?
Miles per Hour (mph) is a unit of speed. Miles per hour measure speed as miles traveled in one hour. One mile equals 1,609.344 meters, so 1 mph equals approximately 0.44704 meters per second [bipm-si-brochure]. This unit is widely used for vehicle speed and speed limits in non-metric countries. Miles per hour originated from the mile and hour units standardized in the British Imperial system. It became common in transportation with the rise of automobiles and was internationally recognized with the mile's 1959 definition [bipm-si-brochure]. The USA, United Kingdom, and several Commonwealth nations use mph for road speed limits and vehicle speeds. It remains standard in aviation and motorsports within these countries, despite metrication efforts [nist-sp-811].
Common Misspellings
People often search for this conversion using these alternate spellings: nautical miles per hour, knots, knotts, knots per hour, miles per hour, mile per hour, mi/h, mphs. All of these refer to the Nautical Miles per Hour to Miles per Hour conversion.
