How to convert speed of lights to mach (sea level)s

Multiply the number of speed of lights by 880991.089953 to get mach (sea level)s.

Speed of light: Exactly 299 792 458 m/s — this is what defines the meter.

Mach (sea level): Speed of sound in the ISA standard atmosphere at sea level, 15 °C. Falls with altitude, so Mach is not a fixed speed.
