Second [s] to Nanosecond [ns] Converter

Quick Reference

1 Second (s) = 1000000000 Nanosecond (ns)

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

How to Convert Second to Nanosecond

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

To convert Second to Nanosecond, multiply the value by 1000000000. To convert Nanosecond back to Second, divide by 1000000000.

Example: convert 10 s to ns:
10 s = 10 x 1000000000 = 10000000000 ns

↔ Convert Nanosecond to Second

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

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.

Common pairs of Time

Second [s] to Nanosecond [ns] Converter

What is 1 s in ns?
1 Second (s) equals 1,000,000,000 ns, and 1 ns equals 0.000000001 s.
How do I convert Second to Nanosecond?
Multiply by 1,000,000,000: 10 s × 1,000,000,000 = 10,000,000,000 ns. The converter above does it for any value, with the precision you choose.
What is 100 s in ns?
100 s = 100,000,000,000 ns. Common amounts are listed on this page, each with its own step-by-step page.
Is a Second bigger than a Nanosecond?
Yes. 1 s = 1,000,000,000 ns, so the same quantity becomes a larger number when written in ns.
