| 10 mph | 14.666667 ft/s |
| 100 mph | 146.666667 ft/s |
| 1,000 mph | 1,466.666667 ft/s |
Use this page to convert miles per hour into feet per second. It is useful when a road, sports, or vehicle speed needs to be used in short-interval motion analysis, engineering, ballistics, or stopping-distance calculations.
Miles per hour is useful for travel speed; feet per second is useful for short-interval motion.
The conversion is common in vehicle safety, sports analysis, and engineering.
Feet per second shows how far something moves each second.
Miles per hour remains clearer for road signs and public travel speeds.
Use consistent feet-and-seconds units in downstream calculations.
This page converts speed only.
Miles per hour works well for driving, but it is not ideal for second-by-second motion.
Feet per second makes it easier to calculate how far something travels in a short time.
That is why the conversion is common in stopping-distance, sports, and engineering problems.
At 60 mph, an object travels 88 feet every second.
That makes ft/s more intuitive when evaluating reaction time or impact distance.
Use mph for communicating speed and ft/s for calculating short-interval movement.
1 mph should equal exactly 1.4666667 ft/s.
60 mph should equal exactly 88 ft/s.
If 1 mph becomes 0.681818 ft/s, the conversion direction has been reversed.
Definition: Miles per hour measures miles traveled in one hour.
History/Origin: Miles per hour is used for road speeds in the United States and the United Kingdom, plus vehicle, weather, and sport references.
Current use: mph is used for road signs, vehicle dashboards, weather reports, aviation references, sports speeds, and travel estimates in mph-based regions.
Definition: Feet per second measures how many feet are traveled in one second.
History/Origin: Feet per second is used in US customary engineering, ballistics, fluid flow, motion analysis, and technical calculations.
Current use: fps is used for motion analysis, engineering, ballistics, flow rates, physics examples, impact speeds, and short-interval speed data.

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.
One mile per hour is exactly 1.46666666667 feet per second.
60 mph is exactly 88 feet per second.
Feet per second is better for short-time motion, engineering, stopping distance, and calculations based on seconds.
