How to Convert Days to Nanoseconds

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

Since one day is equal to 86,400,000,000,000 nanoseconds, you can use this simple formula to convert:

nanoseconds = days × 86,400,000,000,000

The time in nanoseconds is equal to the days multiplied by 86,400,000,000,000.

For example, here's how to convert 5 days to nanoseconds using the formula above.
5 day = (5 × 86,400,000,000,000) = 4.32E+14 ns

How Many Nanoseconds Are in a Day?

There are 86,400,000,000,000 nanoseconds in a day, which is why we use this value in the formula above.

1 day = 86,400,000,000,000 ns

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


One day is the time it takes for the Earth to complete a single rotation around its axis in relation to the Sun. There are 24 hours in a day.

The day is an SI accepted unit for time for use with the metric system. Days can be abbreviated as day; for example, 1 day can be written as 1 day.


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.
