How to Convert Nanoseconds to Years

To convert a nanosecond measurement to a year measurement, divide the time by the conversion ratio.

Since one year is equal to 3.1557E+16 nanoseconds, you can use this simple formula to convert:

years = nanoseconds ÷ 3.1557E+16

The time in years is equal to the nanoseconds divided by 3.1557E+16.

For example, here's how to convert 5.0E+16 nanoseconds to years using the formula above.
5.0E+16 ns = (5.0E+16 ÷ 3.1557E+16) = 1.584437 yr

Nanoseconds and years are both units used to measure time. Keep reading to learn more about each unit of measure.


The nanosecond is a multiple of the second, which is the SI base unit for time. In the metric system, "nano" is the prefix for 10-9. Nanoseconds can be abbreviated as ns; for example, 1 nanosecond can be written as 1 ns.


One year is the time it takes for the Earth to complete its orbit around the Sun. There are 365 days in a year, with the exception of the leap year when there are 366.

Years can be abbreviated as yr, and are also sometimes abbreviated as y. For example, 1 year can be written as 1 yr or 1 y.
