Miles per hour measures miles traveled in one hour.
Miles per hour is used for road speeds in the United States and the United Kingdom, plus vehicle, weather, and sport references.
mph is used for road signs, vehicle dashboards, weather reports, aviation references, sports speeds, and travel estimates in mph-based regions.
Feet per second measures how many feet are traveled in one second.
Feet per second is used in US customary engineering, ballistics, fluid flow, motion analysis, and technical calculations.
fps is used for motion analysis, engineering, ballistics, flow rates, physics examples, impact speeds, and short-interval speed data.
Mathematically, foot per second (ft/s) = mile per hour (mph) converted with the formula below.
1 mph = 1.466667 ft/s
1 ft/s = 0.681818 mph
Formula: value × 1.46666666667
Example: 15 mph = 22 ft/s
Precision note: Use 1.46666666667 feet per second per mile per hour. Keep precision for calculations and round for plain-language display.
