About converting Mile per Hour to Foot per Sec

Converting Mile per Hour to Foot per Sec is a common speed conversion. One mile per hour (mph) equals 1.46667 foot per sec (ft/s). Miles per hour are used for speed limits and weather in the US and UK.

This conversion is commonly needed for physics and engineering calculations, driving and speed limit compliance, running and fitness tracking. Feet per second are used in ballistics, engineering, and some US speed calculations.

To put mile per hour in perspective: a bicycle ride (about 15 mph). In foot per sec, common references include a pitched baseball (about 130 ft/s).

Did you know?

Even though the UK uses miles for road speed limits, it uses kilometers for most other measurements — a split that dates back to an incomplete 1965 metrication effort.

Real-world examples
Mile per Hour (mph)
  • a bicycle ride (about 15 mph)
  • a US highway speed limit (65–75 mph)
  • a cheetah's top speed (about 70 mph)
Foot per Sec (ft/s)
  • a fast elevator (about 20 ft/s)
  • a pitched baseball (about 130 ft/s)
  • the speed of sound (about 1,125 ft/s)
Did you know?

Feet per second is commonly used in ballistics to describe projectile muzzle velocity, giving more intuitively sized numbers than meters per second for that range of speeds.

Common uses for speed conversion

People frequently convert between mile per hour and foot per sec for:

  • driving and speed limit compliance
  • running and fitness tracking
  • aviation and flight planning
  • sailing and marine navigation
  • physics and engineering calculations
