Table of equivalences between ranking systems
Universally valid ranks do not exist; this is a table of approximate rank equivalences.
Please edit it if you have more accurate information than currently presented.
The table starts with beginners and ends with amateur experts.

Related information
Although it is stated above, this does perhaps bear repeating: this table is at best approximate, personal counterexamples abound (see /discussion) and rightly so. The national ranks are arguably likely to be more comparable - they are computed on the grounds of games of a standardised nature, with players in broadly comparable environs; this is markedly not the case on the servers. Where one AGA 4 kyu may play online in an internet cafe, another might have his/her kids running around, the TV on and dinner burning on the stove as they play, or anywhere else for that matter. Perhaps this table should simply remind us:
- ranks are a great advantage of go in allowing decent games between players of different strengths but that is all, and they can become a great distraction,
- don't take absolute ranks too seriously, and
- be prepared to judge handicaps more by the evidence of games and less what the ranks say.
Notes
- European grades vary by country, see
http://www.european-go.org/rating/rgdrep.html. for a comparison of ratings with GoR?. Comparisons of GoR? do not take into account isolated player populations.
- The KGS rating algorithm is given at
http://kgs.kiseido.com/en_US/help/math.html. KGS ratings are no longer anchored to AGA ratings, according to glue's French
KGS FAQ.
- See chapter "International Ranks" in
http://www.cns.nyu.edu/~mechner/go/kyu.html for a summary.
- See also rank - first comments and rank worldwide discussion.
- For rank translations between AGA, China, Europe, Japan, Korea, IGS, NNGS, DGS and IYT see function "convert_to_rating()" in
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).
This site gives a brief list of players and their respective BGA and KGS ranking. It's clearly not scientific in any way, but I think that it does suggest that healthy skepticism is required when thinking about ranks. kokiri
[2] The KGS ranks may not be very well approximated. I used the data from http://kgs.goclub.info/, and from personal experience to interpolate.
