Conversion number between atomic unit of time [au] and year (sidereal) [a, y, or yr] is 7.6648483660572 × 10-25. This means, that atomic unit of time is smaller unit than year (sidereal).
Switch to reverse conversion:
from year (sidereal) to atomic unit of time conversion
| [au] |
Result in year (sidereal)
?If conversion between atomic unit of time to second and second to year (sidereal) is exactly definied, high precision conversion from atomic unit of time to year (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 year (sidereal) unit: ≈ 365.256363004 d. Sidereal year is a time taken for Sun to return to the same position with respect to the stars of the celestial sphere, approximately 365.256363 days.
