Convert foot/second to mile/hour
Please provide values below to convert foot/second [ft/s] to mile/hour [mi/h], or Convert mile/hour to foot/second.
1 ft/s = 0.681818181818 mi/h. To convert foot/second to mile/hour, multiply the value by 0.681818181818; to go the other way, divide by it (1 mi/h = 1.46666666667 ft/s). Both units measure speed and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 ft/s = 0.681818181818 mi/h
- 1 mi/h = 1.46666666667 ft/s
- 10 ft/s = 6.81818181818 mi/h

Foot/second
Foot per second (ft/s) is a unit of speed representing the distance of one foot traveled in one second.
History/Origin
The foot per second has been used historically in engineering, physics, and aeronautics, originating from the imperial measurement system where the foot is a standard unit of length. Its usage predates the metric system and has been common in the United States and other countries using imperial units.
Current Use
Today, ft/s is primarily used in fields such as physics, engineering, and aviation to measure speeds, especially in contexts where imperial units are standard. It is also used in sports and safety standards related to speed measurements.
Mile/hour
Mile per hour (mi/h) is a unit of speed representing the number of miles traveled in one hour.
History/Origin
The mile per hour has been used primarily in the United States and the United Kingdom for measuring speed, especially in transportation, since the adoption of the imperial system. Its usage dates back to the widespread use of miles as a distance measure before metric standardization.
Current Use
Today, mi/h is commonly used in the United States and some other countries to express vehicle speeds, speed limits, and other transportation-related velocities. It remains a standard unit in contexts where the imperial system is prevalent.
