About converting Foot per Sec to Km per Hour

Converting Foot per Sec to Km per Hour is a common speed conversion. One foot per sec (ft/s) equals 1.09728 km per hour (km/h). Feet per second are used in ballistics, engineering, and some US speed calculations.

This conversion is commonly needed for running and fitness tracking, aviation and flight planning, sailing and marine navigation. Kilometers per hour are used for road speed limits in most countries outside the US.

To put foot per sec in perspective: a fast elevator (about 20 ft/s). In km per hour, common references include a highway speed limit (100–120 km/h).

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.

Real-world examples
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)
Km per Hour (km/h)
  • a jogger (about 10 km/h)
  • a highway speed limit (100–120 km/h)
  • a high-speed train (300+ km/h)
Did you know?

Most of the world sets speed limits in kilometers per hour, with the notable exceptions of the United States, the United Kingdom, and a handful of other countries.
