Table of approximate equivalences between ranking systems

Please help to improve this table by adding data to our /DataCollection and feel free to edit it if you have more accurate information than currently presented.

However, since universally valid ranks do not exist; this is and will always be a table of approximate rank equivalences.

The table starts with beginners and ends with amateur experts.

Problems with the table presented above

Be very aware that the information in this table is at best an approximation, and is not very reliable.

  • Older data points used to create the table have not been removed when the relevant ranking system changed.
  • AGA ranks vary internally in the USA, one coast is said to be stronger than the other.
  • EGF ranks vary internally in Europe. A large range of methodologies exist to allocate ranks, ranging from Anarchy to Strict Implementation of the GoR formula. Selecting a country from [ext] this page at the EGD will display a graph comparing that country's ratings versus standard GoR.
  • Likewise ranks are awarded differently in provinces in China, and it is undoubtably the case in Japan and Korea too.
  • The whole list expresses strength differences only with integers, hence might be off by half a dan grade (China)
  • Blitz internet ranks and ranks derived from slower time limits online are often markedly diverse.
  • Turn based servers can suffer from novices improving far faster than the rating system can cope with. (This is also a problem in EGF territories which use a strict implementation of GoR with no rating resets.)
  • The ranks below 20kyu do not exist in some countries in Europe.
  • Some people will play whilst drinking online
  • Some people will play online whilst distracted by children, siblings, or parents.
  • The internet can also contain sandbaggers, players who are deliberately playing under their strength in order to beat up weaker players. The IGS rank of 30kyu used to be notorious for this.
  • There is no data for South America or Australasia. [2]
  • The AGA has no ranks at all, just numerical ratings. There is no official translation between numerical ratings and ranks.

Footnotes

[1] BC (Beginners Class) is a blanket initial rank at IGS. Unranked people & guests start as BC for their first 5 games at least. The first numbered IGS rank appears to be 17kyu currently. There are also some stronger players who choose to have a BC rank.
[2] xela: As I understand it, Australian ranks are set by consensus within each go club. There are not enough tournament games for accurate calculations in the style of American and European ranks. It's generally believed that Australian kyu ranks sit somewhere between the American and Japanese ranks. High dan ranks are possibly a bit stronger (Australian 7 dans seem to hold their own against other 7 dans at the WAGC), and so it's likely that the spacing between dan ranks is greater than one handicap stone per rank. Possibly someone else will have more accurate data on this.
[3] A European 7D grade is claimed to be the approximate equivalent to a professional 1D grade by the EGF.
[4] This column represents the rankings as used by the Hankuk Kiwon, for information on the old gup ranks, see rank - gup (Korean) explained
[5] Ranks on CyberORO depend on the server you play on: On the Japanese server the ranks tend to be better than on the Korean servers.
