How to convert mach (sea level)s to speed of lights
Multiply the number of mach (sea level)s by 0.00000113508525955 to get speed of lights.
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.
Speed of light: Exactly 299 792 458 m/s — this is what defines the meter.
