The entries for "kph" and "kmph" in the Oxford Advanced Learner's Dictionary state that "the correct scientific unit is km/h and this is the generally preferred form". While these forms remain widely used, the International Bureau of Weights and Measures uses "km/h" in describing the definition and use of the International System of Units. Several other abbreviations of "kilometres per hour" have been used since the term was introduced and many are still in use today for example, dictionaries list "kph", "kmph" and "km/hr" as English abbreviations. The SI representations, classified as symbols, are "km/h", " km h −1" and " km The Dutch on the other hand adopted the kilometre in 1817 but gave it the local name of the mijl ( Dutch mile). In 1802 the term " myriamètres par heure" appeared in French literature. The kilometre per hour ( SI symbol: km/h non-standard abbreviations: kph, km/hr) is a unit of speed, expressing the number of kilometres travelled in one hour.Īlthough the metre was formally defined in 1799, the term "kilometres per hour" did not come into immediate use – the myriametre ( 10,000 metres) and myriametre per hour were preferred to kilometres and kilometres per hour.

How to convert Kilometers per hour to Miles per hour? that corresponded to different distance in different time periods and locations.
The Roman mile was 5,000 long, and there were other miles like the English mile, Irish mile, Italian mile, etc. While the kilometer is a modern unit, the mile has a long history, dating back at least far as the Romans. The difference is that the mile is a part of the imperial unit system, used in several countries like the United States and the United Kingdom, while the kilometer is a unit from the metric system. Since the time dimension is in hours for both speed units, the only difference remains that between the length units. Difference between Kilometers per hour and Miles per hourīoth kilometers and miles are units for measuring distances and they are of comparable magnitude. The internationally recognized symbol for kilometer is "km", and "mi" for mile, translating to "kmph" (often "kph") and "miph" which is more often abbreviated to "mph", causing potential confusion with meters per hour. These are internationally agreed upon unit definitions that were established by a treaty signed in 1959. Since the time measurement unit is the same, an hour, it plays no role in the conversion. This follows from the definition of a mile as 5280 feet, the definition of a feet as 0.3044 meters, and the definition of a kilometer as 1,000 meters.
