Establish how many British Pounds you want to convert to Australian Dollars.
Establish the current rate at which British Pounds are exchanging for Australian Dollars. For instance, on April 4, 2011, one British Pound was exchanging for 1.5594 Australian Dollars.
Multiply the amount of British Dollars you wish to convert times the current exchange rate to establish the amount of Australian Dollars to which your Pounds will convert. Example: "120 X 1.5594 = 187.128"
