It's been a long while and I don't remember the formula to convert between these ELO Formats, BCF - USCF - FIDE
Example: 207 BCF = ???? USCF = ???? FIDE
Thanks in Advance
PS: I just found this chart, is it about right?

Re: Rating formula to convert BCF - USCF -FIDE
Is BCF an 'Elo format'?
One thing that disturb any formula for making a list is that different nations use different rating floor, so trying to calculate this for lower rating is difficult (impossible). Ex. Fide's floor is now 1400 I think, just a few years ago it was 2200. I think it will take some time before a Fide rating below 2200 are accurate. Ex. if I compare norwegian rating with Fide rating for players above 2300 it is almost the same (if they are active in both ratingsystem), but if I look at players around 1500 in norwegian rating they can have as high as 2100 in the Fide list. Norway have a floor at 400.
Another way to look at it is to see what average rating is in different systems, a full Elo system should have this around 1400. USCF's rating I think have an average about this. Norwegian average are around 1420-1440.

I think your table is right. USCF is about 100 points higher than FIDE.

BCF is actually now ECF (Britain split up chess into an ENglish, Scottish and Welsh (and N. Ireland?) boards I think)
Not sure of the conversion

I think I recall a while back reading something about the standard formula (elo=8*ecf+600) being modified either for the top or the bottom set of players? (To try to make it more accurate.)
You could check out the ECF website at http://www.englishchess.org.uk/
Personally I think it's crazy that we use a different system!

Ha! But we Germans can top that craziness! For years we used the "Ingo" system, where you rank higher if your value is lower!!MartinBryant wrote:I think I recall a while back reading something about the standard formula (elo=8*ecf+600) being modified either for the top or the bottom set of players?
