How to Convert Microseconds to Milliseconds

conversion scale showing microseconds and equivalent milliseconds time values

To convert a microsecond measurement to a millisecond measurement, multiply the time by the conversion ratio. One microsecond is equal to 0.001 milliseconds, so use this simple formula to convert:

milliseconds = microseconds × 0.001

The time in milliseconds is equal to the microseconds multiplied by 0.001.

For example, here's how to convert 5 microseconds to milliseconds using the formula above.

5 µs = (5 × 0.001) = 0.005 ms

Microseconds and milliseconds are both units used to measure time. Keep reading to learn more about each unit of measure.

Microseconds

The microsecond is a multiple of the second, which is the SI base unit for time. In the metric system, "micro" is the prefix for 10^-6. Microseconds can be abbreviated as µs, for example 1 microsecond can be written as 1 µs.

Milliseconds

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 10^-3. Milliseconds can be abbreviated as ms, for example 1 millisecond can be written as 1 ms.
