Milliseconds to seconds

1 millisecond in seconds
1 ms = 0.001 s
s = ms × 0.001

To convert milliseconds to seconds, multiply by 0.001. The table below gives the values people look up most often, and the converter works for any number.

Milliseconds to seconds table

Common millisecond values converted to seconds.
Milliseconds Seconds
1 ms 0.001
2 ms 0.002
3 ms 0.003
4 ms 0.004
5 ms 0.005
10 ms 0.01
15 ms 0.015
20 ms 0.02
25 ms 0.025
30 ms 0.03
40 ms 0.04
50 ms 0.05

1,000 ms 1

How the conversion works

The relationship is s = ms × 0.001. Both units measure time, so the conversion is a fixed factor that never changes.

Common questions

How many seconds are in one millisecond?
One millisecond equals 0.001 seconds. s = ms × 0.001.
How do you convert milliseconds to seconds?
Use s = ms × 0.001. So 10 ms is 0.01 s.
How many milliseconds are in one second?
One second equals 1,000 milliseconds, which is the reverse of the conversion above.
