Convert Milliseconds to Microseconds
1 millisecond is 1,000 µs. One millisecond is exactly 1000 microseconds.
One millisecond is 1000 microseconds. To convert milliseconds to microseconds, multiply by 1000; to go the other way, divide by 1000 or multiply by 0.001. The factor is exact rather than rounded: it follows from BIPM SI Brochure. One thousandth of a second.

Factors are entered by hand from BIPM SI Brochure rather than derived from a units library, so the ones that terminate are exact rather than rounded.
How do you convert milliseconds to microseconds?
- 1.Take the measurement in milliseconds.
- 2.Multiply by 1000 — that is how many microseconds fit in one millisecond.
- 3.To go back the other way, divide by 1000, or multiply by 0.001.

What are milliseconds and microseconds?
- Millisecond (ms)
- One thousandth of a second. Human reaction time runs about 250 ms, and a frame at 60 fps lasts 16.7 ms.
- Microsecond (µs)
- One millionth of a second. The scale audio latency and network round trips inside a data centre are measured on.

Questions people actually ask
- How many microseconds are in a millisecond?
- 1000. One millionth of a second. The scale audio latency and network round trips inside a data centre are measured on.
- How do I convert microseconds back to milliseconds?
- Divide by 1000, or multiply by 0.001 — they are the same operation.
