The ratings in chess.com do not equate with FIDE or USCF ratings. The amount they differ depends on how much the online player uses all the tools available.
For example, my chess.com rating is probably 500-600 points higher than my OTB rating would be because I make full use of databases, my 70+ chess books, the analysis board, the time available for each move and the notes tab. Someone who plays online chess just as they would OTB may have a rating that is very close to their OTB rating.
The chess.com ratings are only good for comparing chess.com players against each other. They do not directly translate to any other system, no matter what formula you apply.
It might be bad but it's my sense of humor
