Conversion number between day (sidereal) [d (sidereal)] and second [s] is 86164.090530833. This means, that day (sidereal) is bigger unit than second.
Switch to reverse conversion:
from second to day (sidereal) conversion
| [d (sidereal)] |
Result in second
?If conversion between day (sidereal) to second and second to second is exactly definied, high precision conversion from day (sidereal) to second 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!
