You can get far with a simple pocket calculator. If you have 10g of
hops with 4.5 % of alpha, you have 4.5% of 10g = 0.45g of alpha. if your
actual hops are at 5.5%, you need 0.45g of alpha out of them, so you
divide 0.45 by 0.055 (5.5%), and get 8.18 g. Use 8g of the hops instead.
Another way to look at it: Your new hops are 20% stronger, so use 20%
less.
Even easier: Forget the whole analysis - there are far too many
uncertainties in the whole process anyway, you never know how much of
the bitterness gets extracted anyway, and even well trained people can
not distinguish small differences in bitterness. use as many grams as
the receipe says, and worry about something else, because
it will be beer anyway
