1 mph is equal to:

• mile/3600 m·s^-1, the SI derived unit
• mile/1000 km/h
• 22/15 =mile/foot/3600 feet per second

When 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 U.S., Britain and various other nations including overseas territories.
