The second is the SI base unit of time, defined by the fixed value of the cesium-133 hyperfine transition frequency: exactly 9,192,631,770 cycles.

What is a Nanosecond?

The nanosecond is a unit of time equal to 10⁻⁹ seconds — one billionth of a second.

Where is Second used in everyday life?

How to Convert Second to Nanosecond

To convert seconds to minutes: divide by 60. To convert to hours: divide by 3,600. To milliseconds: multiply by 1,000.

1 s = 1,000 ms = 10⁶ µs = 10⁹ ns. There are 60 seconds in a minute and 86,400 in a day.

For example, 1 Second (s) = 1000000000 Nanosecond (ns).
