Light is approximately 874,030 times faster than sound at sea level.
Multiply by 1.14408x10^-6. For example, 874,030x sound = 1c.
Light is an electromagnetic wave traveling at the fundamental speed limit of the universe. Sound is a mechanical wave limited by the properties of its medium.
LEO velocity (~7.8 km/s) is about Mach 22.7, still only 0.0026% the speed of light.
