About Nanosecond
One nanosecond is one billionth of a second. CPU timings and optics may reference nanoseconds.
About Second
The second is the SI base unit of time (scientific definition via atomic clocks). This tool uses fixed-length seconds for conversion.
How to convert nanoseconds to seconds
1 nanosecond is equal to 1.00000000e-9 second:
1 ns = (1e-9 s ÷ 1 s) s = 1.00000000e-9 s
Each nanosecond is defined as 1e-9 s and each second as 1 s, so one ns equals 1e-9 ÷ 1 s = 1.00000000e-9 s.
Let t(ns) be the numeric value of the same duration measured in Nanosecond (ns), and t(s) the value in Second (s). Then:
t(s) = t(ns) × (1e-9 / 1)
Equivalently, divide by how many ns fit into one s (seconds per s divided by seconds per ns):
t(s) = t(ns) ÷ 1.00000000e+9
Or: second = nanosecond ÷ 1.00000000e+9
Examples
Example #1: Convert 20 ns to second
20 ns = 20 ns × (1e-9/1) s = 0.00000002 s
20 ns = 20 ns ÷ 1.00000000e+9 = 0.00000002 s
Example #2: Convert 50 ns to second
50 ns = 50 ns × (1e-9/1) s = 0.00000005 s
50 ns = 50 ns ÷ 1.00000000e+9 = 0.00000005 s
Summary
To convert Nanosecond to Second, multiply the value in ns by the ratio of seconds per ns divided by seconds per s. Equivalently: value_s = value_ns × (1e-9 / 1). Numerically, 1 ns equals 1e-9 s.
Relationship context
You are converting between subsecond precision (milliseconds and smaller) (Nanoseconds) and hours, minutes, and seconds (Seconds). Very large and very small steps share the same second-based definitions here. The numeric factor is 1.000000e-9.
