Look up the latest rate for pound to Aussie dollar conversion (see Resouces).
Multiply the number of pounds you want to convert by the conversion rate. For example, if you wanted to convert one pound into Aussie dollars and the conversion rate was 1.7, you would multiply one pound times 1.7.
Change the units of the number you calculated in Step 2 to Aussie dollars. You have your answer.
Visit an online currency converter website (see Resources). The method for using each site varies slightly.
