Master of Public Health,
Metroid Prime: HuntersMiles per hour is a
unit of
speed, expressing the number of
international miles covered per
hour. It is commonly abbreviated in everyday use in the
United States, the
United Kingdom, and elsewhere to
mph or
MPH, although
mi/h is sometimes used in technical publications .
The preferred
SI unit for velocity is
m·s-1. Speeds are often quoted in
km/h especially in mainland
Europe,
Australia and elsewhere. Nautical and aeronautical applications usually favour the
knot as a unit of speed: one knot is one nautical mile per hour.
1 mph is equal to:

1.609344 km/h* 22/15 =
1.4667 feet per second* approx. 0.868976
knotsWhen converting miles per hour to another unit of measurement, or vice versa, it helps a lot 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
meters. Likewise, 1 hour is equal to 60
minutes, or 3,600
seconds.
Miles per hour is the
unit used for
speed limits on
roads in the United Kingdom, United States and various other nations including overseas territories.
