CONVERSION BETWEEN FIDE ELO, OTHER NATIONAL ELO RATINGS AND ECF GRADINGS The following conversion applies to national Elo ratings and for FIDE Elo ratings greater than 2327:
(Elo - 600) / 8 = ECF
ECF x 8 + 600 = Elo
For FIDE ratings lower than this, and for ECF Grading purposes only, a different formula is used:
(FIDE - 1250) / 5 = ECF
ECF x 5 + 1250 = FIDE

Does anybody know a good way to convert English (ECF) grades into FIDE and/or Chess.com grades? I've only just joined so I don't want to enter any rating capped tournaments until I have a good estimate for my grade, as this would feel like cheating. My official ECF rating is 104 and my actual playing strength is probably closer to ECF grade 120. Can someone help?
