Ecery recipe you come across will always need some sort of conversion. Here's a quote from BIABrewer...
Whether you BIAB, batch-sparge or fly-sparge, any recipe you see on the net or in a book needs to be converted to your own equipment's evaporation rate, efficiency and batch size. The only time that a recipe would never need any adjustments is if the brewer whose recipe you were using happened to have exactly the same evaporation rate, efficiency and batch size that you have/want. This, of course, is never the case.
Yeasty's excellent at recipe conversion so you are in safe hands. When he asks for your kettle diameter, he will use this to estimate your kettle evaporation rate. If you already know from your extract brewing, how many litres you boil off in an hour from your kettle, you can give him this figure instead.
Unfortunately, I don't think there are any calculators around for Mac at the moment although I believe the new BIABacus being developed will eventually run in Libre or Open Office.
