# Extensive Definition

The mile per hour is a unit of
speed, expressing the
number of international miles
covered per hour.

It is currently the unit
used for speed limits,
and speeds, on roads in the
United
Kingdom, United
States and other nations. It is also used to express the speed
of delivery of a ball in various sporting events, such as cricket, tennis, and baseball at the higher levels
of competition. A common abbreviation is mph or MPH, although mi/h
is sometimes used in technical publications.

In the
International System of Units (SI), the unit of speed or
velocity is m/s.
Road traffic speeds, in most countries, are quoted in km/h.
Nautical and aeronautical applications, however, favor the knot as a
common unit of speed: one knot is one nautical
mile per hour.

## 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

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.
