To transform a 2nd measurement come a nanosecond measurement, multiply the time by the switch ratio.

due to the fact that one second is equal to 1,000,000,000 nanoseconds, you have the right to use this simple formula come convert:

You are watching: How many ns in a second

How numerous Nanoseconds room in a Second?

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

1 sec = 1,000,000,000 ns

Seconds and also nanoseconds room both units offered to measure time. Keep analysis to learn more about each unit that measure.


The second has historically been identified as 1/60 the a minute or 1/86,400 the a day. Follow the come SI definition, the second is the expression of 9,192,631,770 periods of the radiation equivalent to the shift between the two hyperfine level of the unperturbed floor state that the caesium 133 atom.<1>

The second is the SI base unit because that time in the metric system. Seconds have the right to be abbreviated together sec; for example, 1 second can be composed as 1 sec.


The nanosecond is a multiple of the second, which is the SI base unit because that time. In the metric system, "nano" is the prefix because that 10-9. Nanoseconds have the right to be abbreviated as ns; because that example, 1 nanosecond can be written as 1 ns.
