When you are purchasing from shops in your own country, you don’t have to worry about currency conversion or currency exchange. But when you want to buy something online from one of the websites that is located in a different country (such as AliExpress from China), you have to think about how much will be the cost of the various things you plan to buy after all the currency conversion.
Problem with currency conversion is that it is not uniform. Local banks often buy the foreign currencies at a lower rate but they sell it at a higher rate. For example, if you are vacationing in Bangkok, Thailand and trying to convert your US dollars into Thai Baht then you will get only 30 Thai Baht for 1 US dollar, but on the other hand they will give you 1 US dollar for 31 Thai Baht.
How do you know exactly how much money you will get when converting it from one currency to another? You can use an app like Imploded Currency Converter using which you can instantly perform currency conversion.
