Conversion number between day (sidereal) [d (sidereal)] and atomic unit of time [au] is 3.5621418348345 × 10+21. This means, that day (sidereal) is bigger unit than atomic unit of time.
Switch to reverse conversion:
from atomic unit of time to day (sidereal) conversion
| [d (sidereal)] |
Result in atomic unit of time
?If conversion between day (sidereal) to second and second to atomic unit of time is exactly definied, high precision conversion from day (sidereal) 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!

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.
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.
