About These Units
Speed of Light (c)
The speed of light in vacuum (c) is exactly 299,792,458 meters per second or approximately 670 million mph. This universal constant is the maximum speed possible in the universe according to Einstein's relativity. Light travels 1 foot in about 1 nanosecond.
Foot per Second (ft/s)
Feet per second (ft/s or fps) measures speed in ballistics, projectile motion, and some US engineering applications. One ft/s equals 0.682 mph or 1.097 km/h. Bullet velocities range from 800-4,000 ft/s. Used for wind tunnel testing and fluid mechanics.
