[edit] Informal usage

  • Early private bank currency issues in French-speaking regions of Canada were denominated in piastres. The term is still unofficially used in Quebec and Acadian slang as a reference to the Canadian dollar (the official French term for the modern Canadian dollar is dollar).
  • Piastre was also the original French word for the United States dollar, used for example in the French text of the Louisiana Purchase and that usage is still common in Cajun French. Modern French uses dollar for this unit of currency as well.
  • The Piastre is still used in Mauritius when bidding in auction sales, similarly to the way that guineas are used at racehorse auctions. It is equivalent to 2 rupees.
