How to convert milliseconds to seconds
To convert milliseconds (ms) to seconds (s), multiply the value in milliseconds by 0.001.
s = ms × 0.001
Example: 10 ms = 0.01 s.
You can also type 10 ms to s into the smart calculator, or mix units: 1 ms + 1 s.

About the units
Millisecond (ms)
One thousandth of a second.
Second (s)
The SI base unit of time, defined by 9,192,631,770 cycles of the caesium-133 hyperfine transition.
The second is the SI base unit of time, defined by the caesium-133 atom. Months and years vary in length, so this converter uses Gregorian averages: a year of 365.2425 days and a month of 30.436875 days. For exact calendar spans between two dates, use the date calculator.
