Chess Rating Comparison, hosted at chessgoals.com, provides a conversion table and interactive calculator for comparing ratings across the major chess rating systems: FIDE, USCF, Lichess, Chess.com, Chess24, and others. Because each system uses different rating floors, pools, and calculation methods, the same player can have substantially different numeric ratings on different platforms.

The tool lets you enter a rating on one system and see approximate equivalents on others, helping players contextualize their standing. The accompanying explanations describe how each rating system works and why the numbers differ, making it educational as well as practical.

The tool is free and requires no account. It is a useful reference for players who are active on multiple platforms and want to understand how their various ratings relate to one another.
