Table of equivalences between ranking systems

World-wide-valid ranks do not exist, but this table of approx rank equivalences. Please edit it, if you have more accurate information than currently presented in this table.

The table starts with beginners and ends with amateur experts.

evpsych: What's the +/- on this? I was under the impression that a 10k nngs is about 17k igs or thereabouts. This table says 10k=10k. +/- 4 stones?

Notes

  • A European 7D grade is believed to be approx equivalent to a professional 1D grade.
  • (1) IGS uses below 28k for "not rated" users and guest logins.
  • For rank translations between AGA, China, Europe, Japan, Korea, IGS, NNGS, DGS and IYT see function "convert_to_rating()" in [ext] DGS server source code. ErikO: The conversions in "convert_to_rating()" are in most cases taken directly from the rank translation table at NNGS (type help rank).

Alex Weldon: I don't believe the ranks given for Gup are accurate; Koreans tell me that nowadays, you go 1 through 7 dan after passing 1 Gup. Perhaps it's been adjusted to match the kyu system


Most online Korean Go servers rankings are inflated by as high as 10~5rankings. However if you play at a Korean club or academy the ranking with an instructor who gives out the rankings it is almost similiar as the table


(July 24 2003) Isn't an update of this list needed now that NNGS has raised rankings by 2 stones? (see help new-ratings on NNGS).

StormCrow: Persuant to the above comment and the bumps in the ranking graphs on NNGS, I've updated the table by increasing all the NNGS rankings by 2 stones.


Alex Weldon: I think either the rankings for KGS, or those for IGS, as given above, are wrong. I was 5k* IGS many months ago, then stopped playing and starting playing on KGS. I lost my first few games, and my rating actually ended up in the low double-digits. I was underrated for sure, and quickly improved back up, but progress has slowed down and I'm still only 6k on KGS (still slightly underrated, since I win about 70% of my games). Meanwhile, my actual skill has improved, so when I decided to try playing on IGS again today, I demolished all my 5k* opponents. So, although the table above shows that KGS ratings are inflated relative to IGS, I think one or the other server must have changed their system, because it seems to be the other way around in my experience.

On the other hand, it may just be a difference in style... maybe my style works better against IGS players. Who knows?


May I remind you that, AGA and EGF rankings are based on wins and losses. Korean, Japanese, and Chinese rankings are based on skills and concepts learned.
