1 nanosecond (ns) = 1e-9 seconds (s). To convert, divide by 1,000,000,000: s = ns ÷ 1,000,000,000. For example, 500,000,000 ns = 0.5 s.
s = ns ÷ 1,000,000,000

The two units
Nanosecond (ns). One billionth of a second, the scale of CPU cycles.
Second (s). The SI unit of time, defined by the caesium-133 atom's hyperfine transition frequency.
