Conversion number between year (Julian) [a, y, or yr] and atomic unit of time [au] is 1.3046345232037 × 10+24. This means, that year (Julian) is bigger unit than atomic unit of time.
Switch to reverse conversion:
from atomic unit of time to year (Julian) conversion
| [a, y, or yr] |
Result in atomic unit of time
?If conversion between year (Julian) to second and second to atomic unit of time is exactly definied, high precision conversion from year (Julian) 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 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.
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.
