### Calculation process of conversion value

• 1 Planck time = (5.39116*10^-44) / (2.418884326509*10^-17) = 2.2287795827677 × 10-27 atomic unit of time
• 1 atomic unit of time = (2.418884326509*10^-17) / (5.39116*10^-44) = 4.4867604124326 × 10+26 Planck time
• ? Planck time × (5.39116*10^-44  ("s"/"Planck time")) / (2.418884326509*10^-17  ("s"/"atomic unit of time")) = ? atomic unit of time

### High precision conversion

If conversion between Planck time to second and second to atomic unit of time is exactly definied, high precision conversion from Planck time to atomic unit of time is enabled.

Since definition contain rounded number(s) too, there is no sense for high precision calculation, but if you want, you can enable it. Keep in mind, that converted number will be inaccurate due this rounding error!

Convert Planck time to other unit:

### Planck time

Definition of Planck time unit: ≡ ( Gℏ⁄c5) 1⁄2. It is the time required for light to travel in a vacuum a distance of 1 Planck length, approximately 5.39 × 10−44 s.

Convert Atomic unit of time to other unit:

### atomic unit of time

Definition of atomic unit of time unit: ≡ a0/(α·c). This is the smallest meaningful time unit under which an electron takes a circle on the first Bohr pitch divided by 2π.
