How the conversion works

Multiply by 0.001 to go from millisecond to second, or divide by it to go back. Every conversion on this site routes through the SI value (s) rather than a table of pairwise factors, so a round-trip returns exactly what you started with.

Going the other way? second to millisecond — 1 s = 1,000 ms.
