The Geary–Khamis dollar (also known as the international dollar) is a hypothetical currency.

As a function

Currency conversions involving PPP can be conceptualized as a 4?-place function taking as parameters:

  • The source currency
  • The target currency
  • The location with respect to the PPP calculation?
  • The year

Only after fixing all four parameters can the unit make sense next to a number.

Of these, the Geary–Khamis dollar partially fixes the parameters except the year.

Difference with the US dollar for a particular year

e.g. 2000 GK dollar vs 2000 US dollar
