About Second
The second is the SI base unit of time (scientific definition via atomic clocks). This tool uses fixed-length seconds for conversion.
About Nanosecond
One nanosecond is one billionth of a second. CPU timings and optics may reference nanoseconds.
How to convert seconds to nanoseconds
1 second is equal to 1.00000000e+9 nanosecond:
1 s = (1 s ÷ 1e-9 s) ns = 1.00000000e+9 ns
Each second is defined as 1 s and each nanosecond as 1e-9 s, so one s equals 1 ÷ 1e-9 ns = 1.00000000e+9 ns.
Let t(s) be the numeric value of the same duration measured in Second (s), and t(ns) the value in Nanosecond (ns). Then:
t(ns) = t(s) × (1 / 1e-9)
Equivalently, divide by how many s fit into one ns (seconds per ns divided by seconds per s):
t(ns) = t(s) ÷ 1.00000000e-9
Or: nanosecond = second ÷ 1.00000000e-9
Examples
Example #1: Convert 20 s to nanosecond
20 s = 20 s × (1/1e-9) ns = 20000000000 ns
20 s = 20 s ÷ 1.00000000e-9 = 20000000000 ns
Example #2: Convert 50 s to nanosecond
50 s = 50 s × (1/1e-9) ns = 50000000000 ns
50 s = 50 s ÷ 1.00000000e-9 = 50000000000 ns
Summary
To convert Second to Nanosecond, multiply the value in s by the ratio of seconds per s divided by seconds per ns. Equivalently: value_ns = value_s × (1 / 1e-9). Numerically, 1 s equals 999999999.9999999 ns.
Relationship context
You are converting between hours, minutes, and seconds (Seconds) and subsecond precision (milliseconds and smaller) (Nanoseconds). Very large and very small steps share the same second-based definitions here. The numeric factor is 1.000000e+9.
