Default Hops Alpha Acid Percentages

Sometimes when a recipe calls for a certain Alpha Acid percentage in the Hops I have to make due with either a higher percentage hops or lower percentage hops from my Home Brew Supplier. Is there a quick and dirty calculator to convert the amount of hops necessary to achieve the same IBU with more/less of a different percentage hops?

Thanks.

Step 1. Calculate AAUs
First, if it's not listed, calculate the AAUs (Alpha Acid Units) for each hop addition in the recipe.

AAUs = (weight in oz.) x (recipe hops AA%)



Step 2. Calculate the required weight of your hops
Then, just divide the AAUs you got in step 1.

(needed weight of your hops in oz) = AAUs / (your hops AA%)
