Converting brewing units

Brewing recipes and equipment mix metric, US and UK units. Choose what to convert, enter a value and pick its unit; the converter shows the value in every other unit of that kind.

US and UK units share names but not sizes: gallons and fluid ounces differ between the two systems, so the converter lists them separately.

Inside Foambyte, you choose metric, US or UK units once in your settings, and every recipe, batch and reading follows them.
