# Millisecond Conversion Calculator

Enter a value in milliseconds below to convert to another unit of time.

## What Is a Millisecond?

A millisecond is a unit used to measure time.

The millisecond is a multiple of the second, which is the SI base unit for time. In the metric system, "milli" is the prefix for thousandths, or 10-3. Milliseconds can be abbreviated as ms; for example, 1 millisecond can be written as 1 ms.

## How Much Is a Millisecond?

One millisecond is equal to 1/1,000 of a second or 1,000 microseconds.

## How to Convert Milliseconds

To convert milliseconds to another unit of time, you need to multiply the value by a conversion factor. A conversion factor is a numerical value used to change the units of a measurement without changing the value.[1]

You can find the conversion factors for milliseconds in the conversion table below.

Then, multiply the time measurement by the conversion factor to find the equivalent value in the desired unit of measurement.

milliseconds × conversion factor = result

You can also use a calculator, such as one of the converters below, for the conversion.
