Convert Milliseconds to Seconds
1 millisecond is 0.001 s. One millisecond is exactly 0.001 seconds.
One millisecond is 0.001 seconds. To convert milliseconds to seconds, multiply by 0.001; to go the other way, divide by 0.001 or multiply by 1000. 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 seconds?
- 1.Take the measurement in milliseconds.
- 2.Multiply by 0.001 — that is how many seconds fit in one millisecond.
- 3.To go back the other way, divide by 0.001, or multiply by 1000.

What are milliseconds and seconds?
- Millisecond (ms)
- One thousandth of a second. Human reaction time runs about 250 ms, and a frame at 60 fps lasts 16.7 ms.
- Second (s)
- The SI base unit of time, fixed since 1967 by the caesium-133 hyperfine transition frequency of 9,192,631,770 Hz.

Questions people actually ask
- How many seconds are in a millisecond?
- 0.001. The SI base unit of time, fixed since 1967 by the caesium-133 hyperfine transition frequency of 9,192,631,770 Hz.
- How do I convert seconds back to milliseconds?
- Divide by 0.001, or multiply by 1000 — they are the same operation.
