How to Convert Milliseconds to Microseconds

conversion scale showing milliseconds and equivalent microseconds time values

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

microseconds = milliseconds × 1,000

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

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

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

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.

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.
