Conversion number between atomic unit of time [au] and second [s] is 2.418884326509 × 10-17. This means, that atomic unit of time is smaller unit than second.
Switch to reverse conversion:
from second to atomic unit of time conversion
| [au] |
Result in second
?If conversion between atomic unit of time to second and second to second is exactly definied, high precision conversion from atomic unit of time to second 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!

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.
Definition of second unit: ≡ 1 s. SI base unit. The second is the duration of 9 192 631 770 periods of the radiation corresponding to the transition between the two hyperfine levels of the ground state of the cesium 133 atom at 0 K temperature.
