How the conversion works
Multiply by 31,557,600,000 to go from year to millisecond, 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? millisecond to year — 1 ms = 3.168808781e-11 yr.
