How the conversion works

Multiply by 365.25 to go from year to day, 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? day to year — 1 d = 0.002737850787 yr.
