1 atomic unit of velocity (a₀Eh/ħ) equals 1.2634974301 astronomical units per day (au/d).

Quick answer

  • 1 atomic unit of velocity = 1.26349743 astronomical units per day
  • 1 astronomical unit per day = 0.7914539248 atomic units of velocity
  • Formula: au/d = a₀Eh/ħ × 1.2634974301

1 atomic unit of velocity = 1.26349743 astronomical units per day

How to convert atomic units of velocity to astronomical units per day

au/d = a₀Eh/ħ × 1.2634974301

To convert atomic units of velocity to astronomical units per day, multiply the number of atomic units of velocity by 1.2634974301.

Example: 1 a₀Eh/ħ to au/d

  1. Start with the value in atomic units of velocity: 1 a₀Eh/ħ.
  2. Multiply by 1.2634974301: 1 × 1.2634974301 = 1.26349743.
  3. Result: 1 atomic unit of velocity = 1.26349743 astronomical units per day.

Going the other way, 1 astronomical unit per day = 0.791453924776 atomic units of velocity, so to convert astronomical units per day back to atomic units of velocity you divide by the same number. See astronomical units per day to atomic units of velocity.
