Why Ingredient Choice Matters

Converting grams (mass) to cups (volume) depends entirely on density. For example, 100g of All-Purpose Flour equals 0.833 cups, whereas 100g of Honey equals only 0.298 cups.

Why Sourcing & Measuring Method Matter

A common cause of failed baking recipes is the assumption that 1 cup of flour has a fixed, universal weight. In reality, King Arthur Baking lists all-purpose flour at 120 grams per cup using the spoon-and-level technique, while the USDA Food Buying Guide lists enriched white flour at 125 grams per cup.

If you scoop flour directly from a bag with a measuring cup, you compress the flour grains, packing up to 140 grams into a single cup. That 20g difference is enough to make cakes dry and tough. Our converter explicitly reveals the exact measurement state and primary reference source for every output.
