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 microseconds box.
- Read the result in seconds as you type, and pick the precision you need.
- Swap the direction to convert back, or copy the result.
How it is calculated
s = µs × 0.000001
Multiply the value in microseconds by 0.000001 to get seconds.
Example
To convert 25 µs to seconds: 25 × 0.000001 = 0.000025 s.

About the units
- Microsecond
- One millionth of a second, exactly 0.000001 s.
- Second
- The SI base unit of time, defined by fixing the caesium-133 transition frequency at 9,192,631,770 Hz.
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 seconds are in one microsecond?
1 µs = 0.000001 s exactly.
How do I convert microseconds to seconds?
Use s = µs × 0.000001. For example, 25 µs = 0.000025 s.
How many microseconds are in one second?
1 s = 1,000,000 µs.
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.
