user9477: Is there a table somewhere that shows how to convert between all the various rating systems?
US Chess seems to indicate that ratings would be converted from others to play in their tournaments.

user9216: This tool converts between USCF and FIDE ratings:

user8751: I assume that you're interested in conversions involving USCF ratings. Here you can see the algorithm used.
As an example the conversion between FIDE and USCF is USCF = 180 + 0.94*FIDE if the FIDE rating is under 2000 and USCF = 20 + 1.02*FIDE if the FIDE rating is over 2000 elo points.

user7726: The official conversion rate for ECF to FIDE is FIDE=7.5*ECF+700, see

Again comments about this being approximate are appropriate.
I don't know of a more general table.
