I'm likely to obtain an ECF rating soon, and for comparison I was wondering how these compare to USCF/FIDE ratings, as of course they are completely different scales.

Thanks for any help.

Ok, thanks for that. The only problem I can see with that formula is that it predicts that if you have an ECF rating of 0, your Elo rating would be 1050- a tad inaccurate at lower grades, then?

EDIT: Ah, that table is better. Cheers.

This is the formula from the BCF website. I can't vouch as to its accuracy. But likely the real deal is not too far off. :)

There's some really strange stuff going on in the ECF regarding conversion rates from ECF to FIDE.  Very little that you read anywhere is totally reliable. It has been recognised that players with ECF ratings were undervalued when given an approximate FIDE rating. The conversion rate has recently been under attack and the subject of reform. If you are below ECF 150-ish it need not concern you, probably any published conversion rate will suffice. The discussion on this subject is too disorganised, nebulous and contradictory for me to venture a firm opinion, despite a conversation with some leading administrators in the English chess world, on this very matter, not three months ago.
