What is Leagues per Hour?

Leagues per Hour (lea/h) is a unit of speed. A league per hour is a unit of speed representing one league traveled in one hour. Traditionally, one league equals three nautical miles (5,556 meters), so one league per hour equals approximately 5.556 kilometers per hour (km/h). This unit is not part of the SI system and is mostly historical [nist-si-guide]. The league originated in the Middle Ages as a measure of distance roughly representing the distance a person could walk in an hour. It was standardized in various countries at different lengths, with the nautical league standardized as three nautical miles during the 19th century [nist-si-guide]. Leagues per hour are now obsolete and rarely used outside historical or literary contexts. Some maritime history references may use leagues for distance, but modern navigation employs knots and kilometers per hour [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: leagues per hour, league an hour, lekue per hour, leage per hour, miles per hour, mile per hour, mi/h, mphs. All of these refer to the Leagues per Hour to Miles per Hour conversion.
