About converting Km per Hour to Foot per Sec

Converting Km per Hour to Foot per Sec is a common speed conversion. One km per hour (km/h) equals 0.911344415 foot per sec (ft/s). Kilometers per hour are used for road speed limits in most countries outside the US.

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

To put km per hour in perspective: a high-speed train (300+ km/h). In foot per sec, common references include a fast elevator (about 20 ft/s).

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.

Real-world examples
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)
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.
