rating conversion ECF

Depends on many things. My ECF is currently 167 but I use chess.com for "batting practice". I play many games, many of which are not part of my repertoire. I don't put as much effort into analysis.

Yes, I'd heard southern ECFs were inflated with respect to more northern ones as well.

I believe the current formula is 700+7.5ECF, putting you at roughly 1700 FIDE, which isn't too far off here, I think. You can only use it as a rough guide, though, partly due to issues with format, partly due to regional differences etc. - if people don't mix between areas much, you will end up with warped ratings. Just play and you'll get a rough idea soon enough.

As an example, I'm 141 ECF and probably play at about 1800 on here when I'm paying attention. However, my ECF is more questionable than most, as I only returned to chess at the start of this year, and a load of my opponents were significantly lower rated, whilst my chess.com rating is lowered by me not actually always paying attention and hanging pieces. Heck, I tend to get myself into trouble and play my way out on here, showing my inconsistency

I'd also advise you not to trust any daily960 rating in the 1800 region, as new players are dropped in at 1800, and this allows people to be notably higher rating than they should in daily960 by winning against 1000ish players rated at 1800.

ECF ratings and chess.com rating measure different things so there isn't really a conversion.  Over the board chess is probably more consistent than online chess.

I've only played 1 tournament of 5 over the board games in the last 20 years and I was unrated for that.  I did have a rating around 20 years ago, but it was just below 100 and I stopped playing for 15 years before restarting on chess.com.

The less said about my 1 match playing over the board for Lancashire the better!  I think that was in an age category rather than rating category though.

What kind of rating system is this?? 3 digit ratings? Ah then Magnus would be just 220 I guess lol

The formula as I understood it most recently on the ECF website was (ECF) * 7.5 + 700.
So ECF of 135 would be (1012+700 = 1712 FIDE). 

Then, in terms of chess.com inflation, Blitz and Rapid tend to be around 200-300 points higher than ones FIDE. So a typical 1700 FIDE player is probably 1900-2000 in blitz, there will be some lower and some even higher.

Uk uses three digit, though we're finally moving to a four digit one. Just the one four digit rating list published, and no otb since because lockdowns. Anyway, 200 is about 2200; Magnus is a bit over 300 I think, the title match in London contributed. The system breaks down at over 250 - or even 200ish - because you don't get that many varied opponents. The three digit system has some advantages, such as easy manual calculation of grades.

1000 ECF = GOD, 1000 FIDE = NOVICE, 1000 USCF = Beginner 1000 CFC = NOOB lol whats this

I'm 138 ECF and I'm 1800 blitz.

the formula is times 7.5 add 700
