Milliseconds to microseconds
Type a value in milliseconds to see it in microseconds straight away, or type in the second box to convert back.

Processing and privacy: The result is calculated inside your browser and your data is not sent to any server.
How to use it
- Type the value in the milliseconds box.
- Read the result in microseconds as you type, and pick the precision you need.
- Swap the direction to convert back, or copy the result.
How it is calculated
µs = ms × 1,000
Multiply the value in milliseconds by 1,000 to get microseconds.
Example
To convert 25 ms to microseconds: 25 × 1,000 = 25,000 µs.

| 5 | 5,000 |
| 10 | 10,000 |
| 20 | 20,000 |
| 25 | 25,000 |
| 50 | 50,000 |
| 100 | 100,000 |
| 250 | 250,000 |
| 500 | 500,000 |
| 1,000 | 1,000,000 |
About the units
- Millisecond
- One thousandth of a second, exactly 0.001 s. It is used for response times and network latency.
- Microsecond
- One millionth of a second, exactly 0.000001 s.
Limits and caveats
- Results are rounded for display and computed with the browser's floating point precision (about 15 significant digits).
- Both unit factors are exact by their official definitions.
Questions about this tool
How many microseconds are in one millisecond?
1 ms = 1,000 µs exactly.
How do I convert milliseconds to microseconds?
Use µs = ms × 1,000. For example, 25 ms = 25,000 µs.
How many milliseconds are in one microsecond?
1 µs = 0.001 ms.
How many days are in a month and a year here?
A year is the average Gregorian year of 365.2425 days and a month is 1/12 of that, 30.436875 days. Results are averages, so use a date calculator for the gap between two specific dates.
How is a Hijri year compared with a Gregorian year?
We use the tabular Islamic calendar average of about 354.367 days, so a Hijri year is roughly 11 days shorter than a Gregorian one. The result is approximate because real Hijri months follow the moon sighting.
