Convert mile/second to foot/second

Please provide values below to convert mile/second [mi/s] to foot/second [ft/s], or Convert foot/second to mile/second.

1 mi/s = 5280 ft/s. To convert mile/second to foot/second, multiply the value by 5280; to go the other way, divide by it (1 ft/s = 0.000189393939394 mi/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 mi/s = 5280 ft/s
  • 1 ft/s = 0.000189393939394 mi/s
  • 10 mi/s = 52800 ft/s
  • 100 mi/s = 528000 ft/s



How to Convert Mile/second to Foot/second

1 mi/s = 5280 ft/s

Example: convert 15 mi/s to ft/s:
15 mi/s = 15 × 5280 ft/s = 79200 ft/s

Mile/second

A mile per second (mi/s) is a unit of speed representing the distance of one mile traveled in one second.

History/Origin

The mile per second has been used primarily in scientific contexts, especially in astronomy and physics, to measure extremely high velocities such as those of celestial objects. Its usage has been limited due to the convenience of metric units in scientific measurement.

Current Use

Today, the mile per second is mainly used in scientific research, particularly in astrophysics and space science, to describe high-velocity phenomena like the speed of spacecraft, stars, or other celestial bodies.


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.
