Miles per hour
From Wikipedia, the free encyclopedia
Miles per hour is a unit of speed, expressing the number of international miles covered per hour.
Miles per hour is the unit used for speed limits, and speeds, on roads in the United Kingdom, United States and some other nations, where it is commonly abbreviated in everyday use to mph or MPH, although mi/h is sometimes used in technical publications.
The SI unit of speed or velocity is m/s. In most countries road traffic speeds are quoted in km/h. Nautical and aeronautical applications usually favor the knot as a unit of speed: one knot is one nautical mile per hour.
[edit] Conversions
1 mph is equal to:
- 0.44704 m/s, the SI derived unit
- 1.609344 km/h
- 22/15 =1.4667 feet per second
- approx. 0.868976 knots
When converting miles per hour to another unit of measurement, or vice versa, it helps to know exactly how miles and hours are related to other units of distance and time, respectively. For example, 1 mile is equal to 5,280 feet, 1,760 yards, or 1,609.344 meters. Likewise, 1 hour is equal to 60 minutes, or 3,600 seconds.
