How to convert second to nanosecond

One second equals 1000000000 ns, so multiply the number of seconds by 1000000000:

ns = s × 1000000000

Going the other way

One nanosecond equals 1.0e-9 s, so to convert back:

s = ns × 1.0e-9

Both directions are shown in the results above, and the drop-downs let you convert between any pair of time units — not just these two.
