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.

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.

How to Convert Millisecond to Nanosecond?

1 Millisecond is equal to 1,000,000,000 Nanosecond. To convert Millisecond to Nanosecond, use this simple formula:

Nanosecond = Millisecond x 1,000,000,000

So, just multiply the number of Millisecond by 1,000,000,000 to get equivalent value in Nanosecond.

Example 1:

Convert 5 Millisecond to Nanosecond
5 x 1,000,000,000 = NaN Nanosecond

Example 2:

Convert 7.5 Millisecond to Nanosecond
7.5 x 1,000,000,000 = NaN Nanosecond
