The
mile per hour is a
unit of
speed, measured
in
Imperial units 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 and United
States. 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.
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.
