Conversion number between sigma and day (sidereal) [d (sidereal)] is 1.1605762839708 × 10-11. This means, that sigma is smaller unit than day (sidereal).
Switch to reverse conversion:
from day (sidereal) to sigma conversion
| sigma |
Result in day (sidereal)
?If conversion between sigma to second and second to day (sidereal) is exactly definied, high precision conversion from sigma 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!

Definition of sigma unit: ≡ 10−6 s. Unit of time equal to one microsecond (1 μs) or 10-6 seconds.
Definition of day (sidereal) unit: ≈ 23 h, 56 min, 4.0916 sec. A sidereal day is the time needed for the Earth to rotate once around its axis so that the distant stars appear in the same position in the sky. This is ~4 minutes shorter than the solar day.
