Nanosecond (ns) - Definition and Overview

What is Nanosecond?

A nanosecond (ns) is an SI unit of time equal to one billionth of a second, that is, 1/1,000,000,000 of a second.

Summary

  • A nanosecond is one billionth of a second
  • It is commonly used in scientific and technical fields to measure time intervals that are extremely short
  • For example, the time it takes for light to travel one foot in a vacuum is approximately one nanosecond.

Second (s) - Definition and Overview

What is Second?

The second(sec,s) is the base unit of time in the International System of Units (SI). It is defined as 1/86400 of a day. Multiples of seconds are usually counted in minutes and hours.

Summary

  • The second is the fundamental unit of time in the International System of Units (SI)
  • It is defined based on the vibrations of cesium atoms
  • One second is the duration of 9,192,631,770 periods of radiation corresponding to the transition between two hyperfine levels of the ground state of the cesium-133 atom.

How to Convert Nanosecond to Second?

1 Nanosecond is equal to 0.000000000001 Second. To convert Nanosecond to Second, use this simple formula:

Second = Nanosecond x 0.000000000001

So, just multiply the number of Nanosecond by 0.000000000001 to get equivalent value in Second.

Example 1:

Convert 5 Nanosecond to Second
5 x 0.000000000001 = 0.000000000005 Second

Example 2:

Convert 7.5 Nanosecond to Second
7.5 x 0.000000000001 = 0.0000000000075 Second
