About these units

Kilometer Per Minute (km/min)

Metric (SI)Current unit

One kilometer per minute is 60 km/h.

Racehorses and greyhounds give this unit a memorable benchmark. Wikipedia lists the top speed of a thoroughbred racehorse or racing greyhound as about 17 m/s, and multiplying by 60 gives 1,020 meters per minute, or 1.02 km/min. A round figure of one kilometer per minute is therefore 60 km/h, a pace such animals roughly reach in a sprint.

One kilometer per minute equals 1,000 m divided by 60 s, or about 16.67 m/s. Its main appeal is mental arithmetic: a vehicle at 60 km/h covers one kilometer every minute, so distances and times can be read off almost directly. The more common road unit, km/h, only replaced the French myriameter per hour during the nineteenth century, with the compound in use in the United States by 1866.

1 kilometer per minute = 16.66666667 meters per second (approximately).

Mile Per Hour (mph)

US & ImperialCurrent unit

Exactly 0.44704 m/s. The unit for road speeds in the US, UK and a few other countries.

Early British motoring law is the best window into this unit. The 1861 Locomotive Act set a limit of 10 mph for light locomotives. The 1865 Red Flag Act cut it to 4 mph in the country and 2 mph in towns, with a person walking ahead with a flag. The Locomotives on Highways Act of 1896 raised it to 14 mph, and the Motor Car Act of 1903 to 20 mph. In 1931 all limits for cars were abolished, and 30 mph in built-up areas returned in 1935.

The mile per hour combines the mile, set at 5,280 feet in Elizabeth I's reign, with the hour, and it equals exactly 0.44704 m/s or 1.609344 km/h. The United Kingdom and United States use it on roads, along with several smaller countries, mostly territories or former territories of those two, and the US, Canada and Ireland use it for rail. Sports such as cricket, tennis and baseball quote ball speeds in it. Aviation and shipping prefer knots, about 0.869 of one mph each.

1 mile per hour = 0.44704 meters per second (exactly).
