1 mph ≈ 0.00131 Mach (at sea level)
変換の理解
Mach number is the ratio of speed to the speed of sound. At sea level and standard temperature (15°C / 59°F), the speed of sound is about 767 mph (1,235 km/h). So 1 mph equals about 1/767 ≈ 0.00130 Mach. Mach 1 is the speed of sound, Mach 2 is twice the speed of sound, etc.
