Milliseconds to Seconds (ms to s) Converter
1 millisecond (ms) = 0.001 seconds (s). To convert milliseconds to seconds, multiply by 0.001: 25 ms × 0.001 = 0.025 s.
Quick facts
- 1 ms = 0.001 s
- 1 s = 1,000 ms
- Formula: s = ms × 0.001
- Quick estimate: multiply by about 0.001
How to convert milliseconds to seconds
- Take the value in milliseconds.
- Multiply it by 0.001 (the number of seconds in one millisecond).
- Round the result to the precision you need.
Worked example: 25 ms × 0.001 = 0.025 s.
To convert seconds back to milliseconds, multiply by 1,000, or divide by 0.001.

What is a millisecond?
One thousandth of a second. Used for computing performance and reaction-time measurements.
What is a second?
The SI base unit of time, defined by a fixed number of cesium atom oscillations. The fundamental unit of time in science and everyday life.
Frequently asked questions
How many seconds are in a millisecond?
There are 0.001 seconds in 1 millisecond (1 ms = 0.001 s).
How many milliseconds are in a second?
There are 1,000 milliseconds in 1 second (1 s = 1000 ms).
How do I convert milliseconds to seconds?
Multiply the number of milliseconds by 0.001. For example, 10 ms × 0.001 = 0.01 s. To convert back, multiply by 1,000.
What is 10 ms in seconds?
10 ms = 0.01 s.
What is 100 ms in seconds?
100 ms = 0.1 s.
Is the conversion exact?
Yes. The factor comes from the official definitions of both units (BIPM SI Brochure (the second). Month and year values are averages, as stated in their definitions). Results are shown to up to 10 decimal places; round them to suit your purpose.
