100 Elo = 0.69 winning expectancy = 1 Go grade

But the Go scale is wider than the chess scale. Here are two
ways to compare both scales.

If you align on the beginners, you get the following table, which
only shows how the Go scale is wider than its chess counterpart,
but is meaningless as an equivalence table:

                       Chess       Go
     Total beginner   1000 Elo   20 Kyu   Total beginner
Typical club player   1500 Elo   15 Kyu
                      2000 Elo   10 Kyu   Typical club player
                      2500 Elo    5 Kyu   Typical club player
  Maximum reachable   3000 Elo    1 Dan
                      3500 Elo    6 Dan
                      4000 Elo    9 Pro   World champions

If you scale the scales, you can get a feeling of how strong
someone is by comparing to the other game:

     Total beginner   1000 Elo   20 Kyu   Total beginner
Typical club player   1300 Elo   15 Kyu
Typical club player   1600 Elo   10 Kyu   Typical club player
Typical club player   1900 Elo    5 Kyu   Typical club player
                      2200 Elo    1 Dan
   Intl GrandMaster   2500 Elo    6 Dan   Best european players
    World champions   2800 Elo    9 Pro   World champions
