1 millisecond equals 1000 microseconds.
A millisecond is one thousandth of a second, while a microsecond is one millionth of a second. Since a microsecond is smaller than a millisecond by a factor of 1000, converting from milliseconds to microseconds involves multiplying by 1000.

Conversion Formula
To convert milliseconds (ms) to microseconds (µs), multiply the value in milliseconds by 1000. This works because 1 millisecond equals 0.001 seconds and 1 microsecond equals 0.000001 seconds. Since 0.001 seconds divided by 0.000001 seconds equals 1000, the multiplier is 1000.
Formula:
microseconds = milliseconds × 1000
Example calculation:
If you have 2 milliseconds:
2 ms × 1000 = 2000 µs
Conversion Example
- Convert 3 milliseconds to microseconds:
- Multiply 3 by 1000
- 3 × 1000 = 3000 µs
- So, 3 milliseconds equals 3000 microseconds
- Convert 0.5 milliseconds to microseconds:
- 0.5 × 1000 = 500 µs
- This means half a millisecond is 500 microseconds
- Convert 10.25 milliseconds to microseconds:
- 10.25 × 1000 = 10250 µs
- Therefore, 10.25 ms equals 10250 microseconds
- Convert 15 milliseconds to microseconds:
- 15 × 1000 = 15000 µs
- So 15 milliseconds is 15000 microseconds

Conversion Definitions
Millisecond: A millisecond is a unit of time equal to one thousandth (1/1000) of a second. It is used in measuring short durations in computing, science, and engineering. The symbol for millisecond is “ms”. It provides a finer scale than a second but larger than a microsecond.
Microsecond: A microsecond is a unit of time equal to one millionth (1/1,000,000) of a second. It is symbolized as “µs” and is used in fields needing extremely precise time measurements, such as electronics and signal processing. It is 1000 times smaller than a millisecond.
Conversion FAQs
What happens if I convert negative milliseconds to microseconds?
Negative milliseconds represent time values before a defined zero point, like timestamps before an event. Multiplying negative milliseconds by 1000 simply converts the negative value to microseconds, preserving the sign and scale.
Can I convert milliseconds to microseconds using division?
No, because microseconds are smaller, you multiply milliseconds by 1000. Dividing would make the value smaller, which is incorrect since 1 ms contains more microseconds, not less.
Are microseconds always larger numbers than milliseconds after conversion?
Yes, since microseconds are 1000 times smaller than milliseconds, the microsecond value is numerically larger when converting from milliseconds by multiplication.
Is the conversion factor always 1000 for all time units?
No, the factor depends on the units involved. For milliseconds to microseconds, it is 1000, but converting seconds to milliseconds uses 1000, and seconds to microseconds uses 1,000,000.
Why do some devices measure time in microseconds instead of milliseconds?
Microseconds provide finer precision, which is necessary for fast processes like CPU operations, signal timing, or data transmissions. Milliseconds may be too coarse for these tasks, causing inaccuracies.
