About Feet per second

Feet per second is an imperial unit of speed used primarily in ballistics, engineering calculations, and some aviation contexts in the United States.

Real-World Examples

  • The muzzle velocity of a typical rifle bullet is about 2,500 feet per second
  • A baseball thrown at 90 mph travels at 132 feet per second
  • Sound travels at approximately 1,125 feet per second in air

💡 Did you know? In ballistics, the speed of a bullet is almost always measured in feet per second (fps), even in countries that use the metric system.

About Kilometers per hour

Kilometers per hour is the most common unit for vehicle speed in the majority of countries. It measures how many kilometers are covered in one hour of travel at a constant speed.

Real-World Examples

  • City speed limits are typically 30 to 50 km/h
  • Highway speed limits range from 100 to 130 km/h in most countries
  • The fastest commercial train (Shanghai Maglev) reaches 431 km/h

💡 Did you know? The Bugatti Chiron Super Sport holds the production car speed record at 490.48 km/h (304.77 mph), achieved in 2019.
