Conversion number between atomic unit of time [au] and day (sidereal) [d (sidereal)] is 2.8072997830151 × 10-22. This means, that atomic unit of time is smaller unit than day (sidereal).
Switch to reverse conversion:
from day (sidereal) to atomic unit of time conversion
| [au] |
Result in day (sidereal)
?If conversion between atomic unit of time to second and second to day (sidereal) is exactly definied, high precision conversion from atomic unit of time to day (sidereal) 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 day (sidereal) unit: ≈ 23 h, 56 min, 4.0916 sec. A sidereal day is the time needed for the Earth to rotate once around its axis so that the distant stars appear in the same position in the sky. This is ~4 minutes shorter than the solar day.
