↔ Convert sidereal days to microseconds instead

🧮 Formula

Microseconds to Sidereal Days
sid d = µs × 1.16058 × 10⁻¹¹
Sidereal Days to Microseconds
µs = sid d × 86,164,090,500

Where

  • µs = the time in microseconds
  • sid d = the time in sidereal days
Every unit here is defined by its time in seconds, so the conversion factor is (seconds per microsecond) ÷ (seconds per sidereal day).
