Conversion number between atomic unit of time [au] and year (Julian) [a, y, or yr] is 7.6649818950395 × 10-25. This means, that atomic unit of time is smaller unit than year (Julian).
Switch to reverse conversion:
from year (Julian) to atomic unit of time conversion
| [au] |
Result in year (Julian)
?If conversion between atomic unit of time to second and second to year (Julian) is exactly definied, high precision conversion from atomic unit of time to year (Julian) 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 (Julian) unit: = 365.25 d average. The basic calendar year has 365 days, but in fact the Earth needs a little more time around the sun. The Julian calendar compensated this with leap year (every fourth year had 366 days). According to the formula, a Julian year has 365 + 1/4 = 365.25 days. But even with this compensation, the astronomical year slip 0.78 days every 100 years into real seasons. Therefore, most countries have moved to the Gregorian calendar introduced in 1582.
