About These Units
Mach (Mach)
Mach number represents speed relative to the speed of sound. Mach 1 equals approximately 1,235 km/h (767 mph) at sea level. Supersonic jets fly at Mach 2+, the Concorde cruised at Mach 2.04. Mach number varies with altitude and temperature. Named after physicist Ernst Mach.
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.
