Can someone please explain to me if there's a formula to calculate elo with the Gliko system (the one that chess.com uses)

That has a link to an article, https://www.chess.com/article/view/chess-ratings---how-they-work
That article has a link to the paper on the Glicko rating system that includes the formulas.

Expected score is 1/ (1 + (10 to the power of (opponent rating - your rating/400)))
Elo change is (Result - Expected score) multiplied by the K factor
