How to Convert Nanoseconds to Seconds

To convert a measurement in nanoseconds to a measurement in seconds, divide the time by the following conversion ratio: 1,000,000,000 nanoseconds/second.

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

seconds = nanoseconds ÷ 1,000,000,000

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

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

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

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.

What Is a Second?

The second has historically been defined as 1/60 of a minute or 1/86,400 of a day. According to the SI definition, the second is the duration of 9,192,631,770 oscillations of the frequency of light emitted from the atomic 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 s, and are also sometimes abbreviated as sec. For example, 1 second can be written as 1 s or 1 sec.
