There are too much countries that use "dollar" to name their currency (between 30 and 40) to fit in the 60 words I am allowed to write here, but you can find a list of these countries when you look at wikipedia if you are searching for "Dollar" (NOT "US Dollar").
A few nations other than the united states use the 'dollar' as their currency. Some of these nations are as follows: Ecuador, El Salvador, and East Timor. All of these nations have adopted the dollar as their national currency!
Those are:Australia,Canada,United States Of America,New Zealand,Bahamian dollar,Barbados dollar,Bermuda dollar,Brunei dollar,Singapore dollar,Jamaican dollar,Fili dollar,Solomon Islands dollar,Namibian dollar,Cayman island dollar,Rhodesian dollar,Brunei dollar,Belize dollar,Guyanesse dollar,Trinidad and Tobago dollarNew Taiwan dollar and i don't know anymore.
Aside from US dollars, there are also Canadian dollar, Singapore dollar and Hong Kong dollar. I don't know if there are more aside from those that I mentioned.
This list is for U.S. Dollars only, which is very different from say a Candian Dollar: American Samoa, Ecuador, El Salvador, Guam, Marshall Islands, Federated States of Micronesia, Northern Mariana Islands, Panama, Puerto Rico, Turks and Caicos Islands, United States of America, United States Minor Outlying Islands, Virgin Islands (US)
