Oh, well, guess we'll have to go with the unsourced and vague quote instead.
In the Middle East and much of Africa, a gold Dinar or Mithqal was 4.25g. In other words, the gold units for Europe, Africa, and the ME were roughly equal.
Meanwhile in South Asia, the Tola was 11.6g or one third of a franc. While in East Asia, the Chinese Tael was 37.5g or ten times the franc.
