Conversion number between year (sidereal) [a, y, or yr] and day (sidereal) [d (sidereal)] is 366.25640181571. This means, that year (sidereal) is bigger unit than day (sidereal).
Switch to reverse conversion:
from day (sidereal) to year (sidereal) conversion
| [a, y, or yr] |
Result in day (sidereal)
?If conversion between year (sidereal) to second and second to day (sidereal) is exactly definied, high precision conversion from year (sidereal) 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!
