Conversion from Millisecond (ms) to Microsecond (µs) and vice versa

Updated on by Stefan Banse

Here you can convert the Time unit Millisecond into the unit Microsecond and vice versa you can convert Microsecond into Millisecond. By clicking the "Swap units" icon, you will always obtain the desired conversion in the calculation result, i.e., ms to µs or µs to ms. With the following calculator you can also calculate any other Time unit.

Info about "Millisecond"

The unit millisecond or thousandth of a second can be traced back to the basic unit second. Here, 1 millisecond corresponds to 0.001 seconds or 1 second corresponds to 1,000 milliseconds. The prefix "milli" in the term millisecond stands for one-thousandth of the base unit second.

This unit belongs to the International System of Units (SI).

For example, while an accuracy of a tenth of a second is sufficient for sprints in athletics to detect the difference between a few centimeters ahead, thousandths of a second in a car race in milliseconds are required to clearly determine the winner.

Info about "Microsecond"

The unit “microsecond” can be traced back to the basic unit second. Therefore, 1 microsecond corresponds to 0.000001 seconds or 1 second corresponds to 1,000,000 microseconds. The prefix "micro" in the term microsecond stands for one-millionth of the base unit second.

This unit belongs to the International System of Units (SI).

A microsecond is often used in scientific and technical applications to measure time. An example from acoustics: the standard hearing frequency of a human is up to 20,000 Hz. 20,000 Hz means that the sound produces 20,000 vibrations per second, or vibrates every 50 microseconds.

Basis for conversion Millisecond (ms) to Microsecond (µs)

The abbreviation for the "Time unit Millisecond" is ms. The abbreviation for the "Time unit Microsecond" is µs.

Formula for the conversion of Millisecond (ms) to Microsecond (µs)

The calculation from Millisecond to Microsecond shall be made using the following conversion formula:

 Conversion formula Millisecond to Microsecond
