How to Convert Days to Nanoseconds

To convert a measurement in days to a measurement in nanoseconds, multiply the time by the following conversion ratio: 86,400,000,000,000 nanoseconds/day.

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 time in days multiplied by 86,400,000,000,000.

For example, here's how to convert 5 days to nanoseconds using the formula above.
nanoseconds = (5 d × 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 d = 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.

What Is a Day?

One day is the time it takes for the Earth to complete a single 360-degree rotation about its axis. 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 d; for example, 1 day can be written as 1 d.

What Is a Nanosecond?

One nanosecond is equal to 1/1,000,000,000 (one-billionth) of a second.

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 billionths, or 10-9. Nanoseconds can be abbreviated as ns; for example, 1 nanosecond can be written as 1 ns.
