How many Canadian dollars equal 25 American dollars?

Answer 1

At the current (2013/01/22 at 04:56 UTC) exchange rate of 1.00 USD = 0.991826 CAD,

25 USD = 25 x 0.991826 CAD

= 24.79 CAD

But if you are exchanging currency you will get charged commission on the exchange, either directly as a percentage (subject to a minimum) or by the exchange rate you get being less than the above, or both*.

*Those places offering "commission free" exchanges are technically lying: if they were truly commission free, if you were to exchange 100 of your local currency into a foreign currency and back again, you should end up with exactly 100 of your local currency (± a few of 0.01 due to rounding errors); however, you should notice the exchange rates are not the same for buying and selling, meaning that you will end up with [significantly] less than 100, and you HAVE been charged commission - just not as a separate fee.
