# Nanosecond

From Wikipedia the free encyclopedia

A nanosecond (ns) is an SI unit of time equal to one billionth of a second, that is, ​11 000 000 000 of a second, or 10−9 seconds.

The term combines the prefix nano- with the basic unit for one-sixtieth of a minute.

A nanosecond is equal to 1000 picoseconds or ​11000 microsecond. Time units ranging between 10−8 and 10−7 seconds are typically expressed as tens or hundreds of nanoseconds.

Time units of this granularity are commonly found in telecommunications, pulsed lasers, and related aspects of electronics.
