To convert milliseconds to sidereal days, multiply the value by 1.16058 × 10⁻⁸. To go the other way, multiply sidereal days by 86,164,100 to get milliseconds.
| Milliseconds (ms) | Sidereal Days (sid d) |
|---|---|
| 1 ms | 1.16058 × 10⁻⁸ sid d |
| 5 ms | 5.80288 × 10⁻⁸ sid d |
| 10 ms | 1.16058 × 10⁻⁷ sid d |
| 25 ms | 2.90144 × 10⁻⁷ sid d |
| 50 ms | 5.80288 × 10⁻⁷ sid d |
| 100 ms | 1.16058 × 10⁻⁶ sid d |
| 250 ms | 2.90144 × 10⁻⁶ sid d |
| 500 ms | 5.80288 × 10⁻⁶ sid d |
| 1,000 ms | 1.16058 × 10⁻⁵ sid d |
| 2,500 ms | 2.90144 × 10⁻⁵ sid d |
| 5,000 ms | 5.80288 × 10⁻⁵ sid d |
| 10,000 ms | 0.000116058 sid d |
| 100,000 ms | 0.00116058 sid d |
| 1,000,000 ms | 0.0116058 sid d |
25 ms × 1.16058 × 10⁻⁸ = 2.90144 × 10⁻⁷ sid d
Try this example →250 ms × 1.16058 × 10⁻⁸ = 2.90144 × 10⁻⁶ sid d
Try this example →Millisecond (ms). A millisecond is one thousandth of a second, used for reaction times and computer timing.
Sidereal day (sid d). A sidereal day (23 h 56 min 4.09 s) is one rotation of the Earth relative to the stars.
There are 1.16058 × 10⁻⁸ sidereal days in one millisecond.
Multiply the number of milliseconds by 1.16058 × 10⁻⁸. For example, 10 milliseconds equal 1.16058 × 10⁻⁷ sidereal days.
One sidereal day equals 86,164,100 milliseconds.
1.16058 × 10⁻⁵ sidereal days. Other common values: 100 milliseconds = 1.16058 × 10⁻⁶ sidereal days and 10,000 milliseconds = 0.000116058 sidereal days.
