Several brewers have asked for the ability to enter pounds and ounces for fermentable weights in the recipe editor. This presents a screen real estate challenge but we will see what we can do. For my part, the scales at the local home brew stores work in pounds, so 7.5 ounces is 0.46 pounds. I have become accustomed to that way of thinking about grain weights. As my brewing as progressed, I have realized that what matters is the percentage of a grain in a batch more than whatever the weight in ounces comes out to. An extra field adds complexity to the interface, which is generally a negative from a usability perspective. However, forcing users to do it 'our way' is a greater evil. Perhaps this will be a per-user option, we can let each user can decide for themselves? Anybody else want to give their thoughts?
