What is Miles per hour?
'''Miles per hour''' is a [[unit of measurement]]. It measures [[speed]]. It is the number of [[mile]]s moved in an [[hour]]. Miles per hour is the unit used for [[speed limit]]s on [[road]]s in the [[United Kingdom]] and the [[United States]]. It is normally [[abbreviation|abbreviated]] in everyday use to '''mph''' or '''MPH'''. In [[technical]] [[publication]]s it is sometimes abbreviated as '''mi/h'''. The [[SI]] unit for [[velocity]] (speed, with a [[direction]] of movement) is [[Metre per second|m·s<sup>−1</sup>]] (metres per second).
