Equivalent to: 0 MPH | 0 km/h
What is Feet Per Second (FPS)?
Feet per second (fps or ft/s) is a unit of both speed (scalar) and velocity (vector). It expresses the distance in feet traveled, divided by the time in seconds. It is a common measurement in physics, engineering, and ballistics within the United States and other countries that use the Imperial system.
The Formula for FPS
The calculation for feet per second is straightforward. You divide the total distance in feet by the total time it took to travel that distance:
Velocity (FPS) = Total Distance (ft) รท Total Time (s)
Practical Examples
- Sprinting: If an athlete runs 100 feet in 4 seconds, their speed is 25 FPS (100 / 4).
- Traffic: A car traveling at 60 Miles per Hour is moving at approximately 88 FPS.
- Ballistics: A typical paintball marker fires at roughly 300 FPS to ensure safety and accuracy.
Speed Conversion Table
