How to Convert Microseconds to Milliseconds

conversion scale showing microseconds and equivalent milliseconds time values

To convert a microsecond measurement to a millisecond measurement, divide the time by the conversion ratio. One millisecond is equal to 1,000 microseconds, so use this simple formula to convert:

milliseconds = microseconds ÷ 1,000

The time in milliseconds is equal to the microseconds divided by 1,000.

For example, here's how to convert 5,000 microseconds to milliseconds using the formula above.
5,000 µs = (5,000 ÷ 1,000) = 5 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.
