Fermentory

Fermentory is a Chrome extension for homebrewers. When a page has a beer recipe, it notices, lets you save it, and scales it to your batch size, converting between gallons and litres and pounds and kilos. It also has brewing calculators and a full-page reader that shows just the recipe, without the ads and the life story. It's free, with an optional one-time Pro upgrade.
