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.

Millisecond (ms) - Definition and Overview

What is Millisecond?

A millisecond (ms) is a thousandth (1/1,000) of a second.

Summary

  • A millisecond is one thousandth of a second
  • It is frequently used in various fields such as audio and video processing, where precise timing is crucial
  • For example, the refresh rate of a computer monitor is often measured in milliseconds.

How to Convert Nanosecond to Millisecond?

1 Nanosecond is equal to 0.000000001 Millisecond. To convert Nanosecond to Millisecond, use this simple formula:

Millisecond = Nanosecond x 0.000000001

So, just multiply the number of Nanosecond by 0.000000001 to get equivalent value in Millisecond.

Example 1:

Convert 5 Nanosecond to Millisecond
5 x 0.000000001 = 0.000000005 Millisecond

Example 2:

Convert 7.5 Nanosecond to Millisecond
7.5 x 0.000000001 = 0.0000000075 Millisecond
