**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

this is going to sound really thick, and I don't know if anyone will see this to anwer it, but are chess.com ratings FIDE ratings? I'm not very informed about this stuff :/

Yep

The 1250 formula seems strange, must be way out of date since 1278 FIDE clearly doesn't equate to 5.6 ECF.

The current formula used is I think:

ECF * 7.5 + 700 = FIDE

or

(FIDE - 700)/7.5 = ECF

which gives 1278 FIDE ~ 77 ECF (a bit more reasonable)

Take it with a pinch of salt - a linear conversion between two rating schemes is of course an approximation, and fits best near the centre of the distribution.

It's funny to mention - this formula is strangely accurate for my current grades. My ECF is 184, which converts to 2080 FIDE. Meanwhile, my actual FIDE just dropped slightly from 2084 to 2078!

They seem to change the formula every five minutes... Why can't England just be like everyone else

Now, where would be the fun in that?

I like our grading system. why do you need numbers in the thousands when a smaller number can do just fine.

good point but why doesn't england be like everyone else??

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?
