Nanosecond [ns] to Second [s] Converter

Quick Reference

1 Nanosecond (ns) = 1.0000e-9 Second (s)

1 Second (s) = 1000000000 Nanosecond (ns)

How to Convert Nanosecond to Second

1 ns = 1.0000e-9 s
1 s = 1000000000 ns

To convert Nanosecond to Second, divide the value by 1000000000 (equivalently, multiply by 1.0000e-9). To convert Second back to Nanosecond, multiply by 1000000000.

Example: convert 10 ns to s:
10 ns = 10 x 1.0000e-9 = 1.0000e-8 s

↔ Convert Second to Nanosecond

Nanosecond

Definition: A nanosecond (ns) is a unit of time equal to one billionth of a second (1 × 10−9 s).

History/origin: The nanosecond is derived from the SI prefix "nano-", which means one billionth. It became relevant with the development of high-speed electronics and computers, where events happen at extremely short timescales.

Current use: Nanoseconds are commonly used in computer science, telecommunications, and physics to measure the duration of very short events, such as the execution time of instructions in a processor, the propagation delay of signals in a circuit, or the lifetime of particles in physics experiments.

Second

Definition: A second (symbol: s) is the base unit of time in the International System of Units (SI).

History/origin: Historically, the second was defined as a fraction of the mean solar day. Today, it is defined based on the radiation frequency of a cesium-133 atom.

Current use: Seconds are a fundamental unit of time used in everyday life, science, and technology for measuring durations, frequencies, and other time-related quantities.

Nanosecond [ns] to Second [s] Converter

What is 1 ns in s?
1 Nanosecond (ns) equals 0.000000001 s, and 1 s equals 1,000,000,000 ns.
How do I convert Nanosecond to Second?
Divide by 1,000,000,000: 10 ns ÷ 1,000,000,000 = 0.00000001 s. The converter above does it for any value, with the precision you choose.
What is 100 ns in s?
100 ns = 0.0000001 s. Common amounts are listed on this page, each with its own step-by-step page.
Is a Nanosecond bigger than a Second?
No. 1 ns is only 0.000000001 s: it takes 1,000,000,000 ns to make 1 s.
