To convert microseconds to Julian years, multiply the value by 3.16881 × 10⁻¹⁴. To go the other way, multiply Julian years by 31,557,600,000,000 to get microseconds.

↔ Convert Julian years to microseconds instead

🧮 Formula

Microseconds to Julian Years
a = µs × 3.16881 × 10⁻¹⁴
Julian Years to Microseconds
µs = a × 31,557,600,000,000

Where

  • µs = the time in microseconds
  • a = the time in Julian years
Every unit here is defined by its time in seconds, so the conversion factor is (seconds per microsecond) ÷ (seconds per Julian year).
