Conversion number between day (sidereal) [d (sidereal)] and year (mean tropical) [a, y, or yr] is 0.0027304336479623. This means, that day (sidereal) is smaller unit than year (mean tropical).
Switch to reverse conversion:
from year (mean tropical) to day (sidereal) conversion
| [d (sidereal)] |
Result in year (mean tropical)
?If conversion between day (sidereal) to second and second to year (mean tropical) is exactly definied, high precision conversion from day (sidereal) to year (mean tropical) 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!
