Convert Milliseconds (ms) to Seconds (s)
1 millisecond equals 0.001 seconds.
Millisecond to Second Converter
How to Convert Millisecond to Second
1 millisecond = 0.001 seconds
Second = Millisecond × 0.001
Example: 1 ms × 0.001 = 0.001 s
Reverse Conversion
To convert seconds back to milliseconds:
- Remember, 1 second equals 1000 milliseconds.
- To convert 0.001 s to ms, multiply
0.001 x 1000, resulting in1 ms.

Definition of Millisecond
- Definition
-
ms — The millisecond is a unit of time equal to one thousandth of a second (0.001 s or 10⁻³ s). It is widely used in computing (response times, frame rates), sports timing (sprint finishes, lap times), telecommunications (network latency), and neuroscience (nerve impulse timing).
The millisecond follows standard SI prefix rules: the "milli-" prefix means 1/1,000.
- Exact factor
- 1 ms = 0.001 s (exact)
- Examples
-
- 1,000 ms = 1 second
- 16.67 ms = 1 frame at 60 fps
- 100 ms = typical human reaction time
Definition of Second
- Definition
-
s — The second is the SI base unit of time. Since 1967, it has been defined as the duration of 9,192,631,770 periods of the radiation corresponding to the transition between the two hyperfine levels of the ground state of the caesium-133 atom.
The second is the only SI base unit with a prefix-ready name. It forms the basis for all other time measurements in the International System of Units, and is fundamental to definitions of the meter (via the speed of light) and the ampere.
- Exact factor
- SI base unit (1 s)
- Examples
-
- 60 s = 1 minute
- 3,600 s = 1 hour
- 86,400 s = 1 day
Frequently Asked Questions
How many seconds are in one millisecond?
One millisecond equals 0.001 seconds. To convert, multiply the millisecond value by 0.001. For the reverse, divide the second value by 0.001 (or multiply by 1000).
What is 100 milliseconds in seconds?
100 milliseconds = 0.1 seconds. This is one of the most commonly searched conversions for this pair.
Is the millisecond-to-second conversion exact?
Yes. The factor 0.001 is exact by international definition, not an approximation. Any imprecision comes only from the original measurement, not the conversion.
