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