Quick answer
- 1 atomic unit of velocity = 6,428.902594 Mach (sea level)
- 1 Mach (sea level) = 0.000155547543 atomic units of velocity
- Formula: Ma = a₀Eh/ħ × 6,428.90259379
1 atomic unit of velocity = 6,428.902594 Mach (sea level)
How to convert atomic units of velocity to Mach (sea level)
Ma = a₀Eh/ħ × 6,428.90259379
To convert atomic units of velocity to Mach (sea level), multiply the number of atomic units of velocity by 6,428.90259379.
Example: 1 a₀Eh/ħ to Ma
- Start with the value in atomic units of velocity: 1 a₀Eh/ħ.
- Multiply by 6,428.90259379: 1 × 6,428.90259379 = 6,428.902594.
- Result: 1 atomic unit of velocity = 6,428.902594 Mach (sea level).
Going the other way, 1 Mach (sea level) = 0.000155547543 atomic units of velocity, so to convert Mach (sea level) back to atomic units of velocity you divide by the same number. See Mach (sea level) to atomic units of velocity.

What is an atomic unit of velocity?
The atomic unit of velocity, about 2,188 km/s, is the speed of an electron in the Bohr model of hydrogen, 1/137 of the speed of light.
What is a Mach (sea level)?
The Mach number is speed as a multiple of the local speed of sound, named after the physicist Ernst Mach.
