    Is it possible to add other currencies or conversions to the calculator?
    Liza Gaylord
    Community Answer
    Not possible, sorry. The calculator that comes installed on Macs is very fixed. You will probably need online calculators to do this. (Google does this very well if you type your needed calculation into the search bar.)
