How to Convert Years to Nanoseconds

Calendars document the days in a month

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

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

nanoseconds = years × 3.1557E+16

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

For example, here's how to convert 5 years to nanoseconds using the formula above.
5 yr = (5 × 3.1557E+16) = 1.5778E+17 ns

How Many Nanoseconds are in a Year?

There are 3.1557E+16 nanoseconds in a year, which is why we use this value in the formula above.

1 yr = 3.1557E+16 ns

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


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.


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.
