Frequently asked questions
How many grams are in a cup?
It depends on the ingredient, because a cup measures volume and grams measure weight. A US cup of all-purpose flour weighs about 125 g, granulated sugar 200 g, packed brown sugar 220 g, butter 227 g, milk 244 g and honey 339 g. Only water comes to roughly one gram per milliliter: a US cup of water is about 237 g.
Why do websites give different cup weights for flour?
Flour packs down, so the weight of a cup depends on how you fill it. USDA measured 125 g for a dipped cup of all-purpose flour; some bakeries use 120 g for flour spooned in and leveled. For the most reliable results, weigh your flour.
Is a US cup the same as a metric cup?
No. A US cup is 236.6 ml and a metric cup (Australia, Canada, New Zealand) is 250 ml, so a metric cup of an ingredient weighs about 5–6% more than the weights here.
Where do these weights come from?
From the USDA National Nutrient Database for Standard Reference (SR Legacy, 2018) in FoodData Central, which lists measured weights of common household portions.
