To m/s (at 20°C): × 343.6. To km/h (at 20°C): × 1,237. Note: changes with altitude and temperature.
Mach = velocity ÷ speed_of_sound. At 20°C: Mach 1 = 343.6 m/s. Speed of sound = √(γRT/M) where γ = heat capacity ratio.
For example, 1 Mach (20°C, 1 atm) (Ma) = 0.000001146126231 Velocity of Light in Vacuum (c).
