0.000000001 seconds
= 2.77778E-13 h= 1.66667E-11 min
equals 0.000000001 secondsFormula: s = ns × 1e-9
Nanosecond to Second formula
s = ns × 1e-9
Convert 5 nanoseconds to seconds
- Start with 5 nanoseconds.
- Multiply by the conversion factor: 5 × 0.000000001 = 0.000000005.
- So 5 ns = 0.000000005 s.

Unit definitions
What is a nanosecond?
The nanosecond is one billionth of a second. It is the timescale of modern computer clock cycles, fibre-optic signalling, and fast electronics. Light travels about 30 centimetres in one nanosecond.
What is a second?
The second is the SI base unit of time, defined by the hyperfine transition frequency of caesium-133. It is the foundation of all timekeeping and the basis for every other time unit. Sixty seconds make a minute.
Frequently asked questions
How many seconds are in one nanosecond?
One nanosecond equals 0.000000001 seconds (1 ns = 0.000000001 s).
How do I convert nanoseconds to seconds?
Multiply the value in nanoseconds by 0.000000001. For example, 10 ns × 0.000000001 = 0.00000001 s.
Which is bigger — a nanosecond or a second?
A second is bigger: one second contains 1,000,000,000 nanoseconds.
Is this nanosecond to second converter free?
Yes — the converter is free, works offline once loaded, and computes instantly in your browser without sending your numbers to a server.
