Foot per second to Mile per hour
Foot per second (ft/s)
Mile per hour (mph)
How it is calculated
Each unit is defined via the base unit (meter per second (m/s)). The value is first converted to the base unit, then to the selected unit.
1 ft/s = 0.3048 m/s
1 mph = 0.44704 m/s
1 ft/s × 0.3048 = 0.3048 m/s
0.3048 m/s ÷ 0.44704 = 0.681818181818 mph
