Seconds to milliseconds

1 second in milliseconds
1 s = 1,000 ms
ms = s × 1,000

To convert seconds to milliseconds, multiply by 1,000. The table below gives the values people look up most often, and the converter works for any number.

Seconds to milliseconds table

Common second values converted to milliseconds.
Seconds Milliseconds
1 s 1,000
2 s 2,000
3 s 3,000
4 s 4,000
5 s 5,000
10 s 10,000
15 s 15,000
20 s 20,000
25 s 25,000
30 s 30,000
40 s 40,000
50 s 50,000
75 s 75,000
100 s 100,000
250 s 250,000
500 s 500,000
1,000 s 1,000,000

How the conversion works

The relationship is ms = s × 1,000. Both units measure time, so the conversion is a fixed factor that never changes.

Common questions

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