How to Convert Seconds to Nanoseconds

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

Since one second is equal to 1,000,000,000 nanoseconds, you can use this simple formula to convert:

nanoseconds = seconds × 1,000,000,000

The time in nanoseconds is equal to the seconds multiplied by 1,000,000,000.

For example, here's how to convert 5 seconds to nanoseconds using the formula above.
5 sec = (5 × 1,000,000,000) = 5,000,000,000 ns

How Many Nanoseconds Are in a Second?

There are 1,000,000,000 nanoseconds in a second, which is why we use this value in the formula above.

1 sec = 1,000,000,000 ns

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


The second has historically been defined as 1/60 of a minute or 1/86,400 of a day. According the to SI definition, the second is the duration of 9,192,631,770 periods of the radiation corresponding to the transition between the two hyperfine levels of the unperturbed ground state of the caesium 133 atom.[1]

The second is the SI base unit for time in the metric system. Seconds can be abbreviated as sec; for example, 1 second can be written as 1 sec.


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.
