Milliseconds to Seconds: the quick answer
1 ms = 0.001 s
1 millisecond equals 0.001 seconds
To convert milliseconds to seconds, multiply the value by 0.001. To go the other way, multiply seconds by 1,000 to get milliseconds.
Enter details
1 millisecond =
0.001 seconds
1 second =
1,000 milliseconds
Formula
s = ms × 0.001
Handy values
100 ms = 0.1 s · 1,000 ms = 1 s · 10,000 ms = 10 s
Conversion at a glance
Formula
Milliseconds to Seconds
s = ms × 0.001
Seconds to Milliseconds
ms = s × 1,000
Where
- ms = the time in milliseconds
- s = the time in seconds
Every unit here is defined by its time in seconds, so the conversion factor is (seconds per millisecond) ÷ (seconds per second).
