- 0.5 nanoseconds – the half-life of beryllium-13.
- 0.96 nanoseconds – 100 Gigabit Ethernet Interpacket gap
- 1.0 nanosecond – cycle time of an electromagnetic wave with a frequency of 1 GHz (1×109 hertz).
- 1.0 nanosecond – electromagnetic wavelength of 1 light-nanosecond. Equivalent to 0.3m radio band.
- 1.016703362164 nanoseconds (by definition) – time taken by light to travel 1 foot in a vacuum.[n 1]
- 3.3356409519815 nanoseconds (by definition) – time taken by light to travel 1 metre in a vacuum.
- 10 nanoseconds – one "shake", (as in a "shake of a lamb's tail") approximate time of one generation of a nuclear chain reaction with fast neutrons
- 10 nanoseconds – cycle time for frequency 100 MHz (1×108 hertz), radio wavelength 3 m (VHF, FM band)
- 10 nanoseconds – half-life of lithium-12
- 12 nanoseconds – mean lifetime of a K meson

- 30 nanoseconds – half-life of carbon-21
- 77 nanoseconds – a sixth (a 60th of a 60th of a 60th of a 60th of a second)
- 96 nanoseconds – Gigabit Ethernet Interpacket gap
- 100 nanoseconds – cycle time for frequency 10 MHz, radio wavelength 30 m (shortwave)
- 299 nanoseconds – half-life of polonium-212
- 333 nanoseconds – cycle time of highest medium wave radio frequency, 3 MHz
- 500 nanoseconds – T1 time of Josephson phase qubit (see also Qubit) as of May 2005
- 1,000 nanoseconds – one microsecond
- 1,000,000 nanoseconds – one millisecond (ms)
- International System of Units
- Jiffy (time)
- Orders of magnitude (time)
- By definition of the "foot" as exactly 1/3 yards, and of the international yard as "exactly 0.9144 metres", and of the metre (SI unit) defined by the International Bureau of Weights and Measures as the "length of the path traveled by light in vacuum during a time interval of 1/299792458 of a second". The time taken by light to travel 1 foot in a vacuum is therefore (1/299792458)x(0.9144/3) seconds, or 1.016703362164 nanoseconds.
