Julian years to Nanoseconds
1 yr ≈ 3.156 × 10¹⁶ ns. Edit either value to convert instantly.
Conversion formula
ns = yr × (31,557,600) × (1 × 10⁹)1 yr ≈ 3.15576 × 10¹⁶ ns
Julian year (yr)
A Julian year is exactly 365.25 days (31,557,600 seconds); this is a fixed-duration convention, while a calendar year has 365 or 366 days.

nanosecond (ns)
A nanosecond is an SI submultiple of the second: 1 ns equals exactly 10^-9 s (1 × 10⁻⁹ s).
