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.
Meter per Second (m/s)
Meters per second (m/s) is the SI derived unit of speed and velocity. One m/s equals 3.6 km/h or 2.237 mph. Meters per second measure wind speed, fluid flow, running pace, and scientific applications. A human walks at about 1.4 m/s, runs at 5-8 m/s.
