1 E-9 s

A nanosecond (ns) is one billionth of a second. "See also" times of other orders of magnitude.

To help compare orders of magnitude of different times this page lists times between 10⁻⁹ seconds and 10⁻⁸ seconds (1 nanosecond and 10 nanoseconds).

* shorter times
* 1.0 nanoseconds (1.0 ns) – cycle time for frequency 1 GHz, radio wavelength 0.3 m
* 1.02 nanoseconds (approximately) – time taken for light to travel 1 foot.
* 3.33564095 nanoseconds (approximately) – time taken for light to travel 1 metre
* longer times

A common computer instruction is 'nanosleep' meaning suspend execution for a length of time given in nanoseconds (for example, http://www.opengroup.org/onlinepubs/007908799/xsh/nanosleep.html)
