Frequently asked questions
Because ingredients have different densities. A cup holds the same volume, but 1 cup of honey weighs 340 g while 1 cup of rolled oats weighs only 80 g. Converting weight to volume without the right density is how recipes go wrong.
Baking recipes almost always mean packed brown sugar unless they say "loosely packed" or "lightly packed". Our table assumes packed (220 g per cup). Unpacked brown sugar is closer to 145 g per cup.
Our densities use the US legal cup (240 ml). A 250 ml metric cup is about 4% larger — multiply the cup result by 1.042. For most recipes that difference is minor, but for large batches it adds up.
