Quick Reference Values
1 km/h = 0.539957 nmi/h. 5 km/h = 2.699786 nmi/h. 10 km/h = 5.399573 nmi/h. 25 km/h = 13.498932 nmi/h. 50 km/h = 26.997863 nmi/h. 100 km/h = 53.995727 nmi/h.
What is Kilometers per Hour?
Kilometers per Hour (km/h) is a unit of speed. Kilometers per hour (km/h) measures speed as the number of kilometers traveled in one hour. It converts directly to meters per second by multiplying by 1000/3600. This unit is standardized internationally for expressing road and vehicle speeds [bipm-si-brochure]. The kilometer per hour unit was adopted alongside the metric system in the 19th century, formalized by the International System of Units (SI) established by the BIPM. It became widespread for transportation speed limits due to metrication efforts in Europe and worldwide [bipm-si-brochure]. Kilometers per hour is the standard speed measurement in most countries, including all European nations, Canada, Australia, and many others. It is used extensively in road traffic regulations, automotive industries, and international transportation standards [nist-si-guide].
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].
Common Misspellings
People often search for this conversion using these alternate spellings: kilometres per hour, kmph, kph, kilometer per hour, km/hr, nautical miles per hour, knots, knotts, knots per hour. All of these refer to the Kilometers per Hour to Nautical Miles per Hour conversion.
