How the conversion works
Multiply by 0.9 to go from gradian to degree, or divide by it to go back. Every conversion on this site routes through the SI value (rad) rather than a table of pairwise factors, so a round-trip returns exactly what you started with.
Going the other way? degree to gradian — 1 ° = 1.111111111 gon.
