### Calculation process of conversion value

• 1 nanoseconds = (exactly) (0.000000001) / (31557600) = 3.1688087814029 × 10-17 year (Julian)
• 1 year (Julian) = (exactly) (31557600) / (0.000000001) = 3.15576 × 10+16 nanoseconds
• ? nanoseconds × (0.000000001  ("s"/"nanoseconds")) / (31557600  ("s"/"year (Julian)")) = ? year (Julian)

### High precision conversion

Definition of nanoseconds unit: ≡ 10-9 s. billionth part or a second

Convert Year (Julian) to other unit:

### year (Julian)

Definition of year (Julian) unit: = 365.25 d average. The basic calendar year has 365 days, but in fact the Earth needs a little more time around the sun. The Julian calendar compensated this with leap year (every fourth year had 366 days). According to the formula, a Julian year has 365 + 1/4 = 365.25 days. But even with this compensation, the astronomical year slip 0.78 days every 100 years into real seasons. Therefore, most countries have moved to the Gregorian calendar introduced in 1582.
