Whats Smaller Than A Nanosecond

Unit of measurement of time

Await up nanosecond in Wiktionary, the costless dictionary.

A nanosecond (ns) is a unit of measurement of fourth dimension in the International System of Units (SI) equal to ane billionth of a 2nd, that is, 1⁄1 000 000 000 of a second, or x⁻⁹ seconds.

The term combines the SI prefix nano- indicating a 1 billionth submultiple of an SI unit of measurement (e.thou. nanogram, nanometre, etc.) and 2d, the primary unit of measurement of fourth dimension in the SI.

A nanosecond is equal to 1000 picoseconds or 1⁄1000 microsecond. Time units ranging betwixt x^−eight 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.

Notes

^ By definition of the "pes" as exactly 1/three yards, and of the international thousand every bit "exactly 0.9144 metres", and of the metre (SI unit) defined past the International Bureau of Weights and Measures every bit the "length of the path traveled by low-cal in vacuum during a time interval of i/299792458 of a second". The fourth dimension taken past calorie-free to travel 1 foot in a vacuum is therefore (one/299792458)ten(0.9144/three) seconds, or i.016703362164 nanoseconds.
