About this cups to grams converter
American recipes measure by volume in cups, while recipes in most other countries weigh ingredients in grams, and a kitchen scale gives far more reliable baking results. A cup is a volume, so how many grams it holds depends on the ingredient: a US cup of all-purpose flour is about 120 g, sugar 200 g, and honey 340 g. This converter uses typical weights for 42 common ingredients, measured the way most bakers do, by spooning dry ingredients into the cup and leveling them off. Choose a metric cup of 250 mL for Australian and many European recipes.

Frequently asked questions
Why does a cup of flour weigh less than a cup of sugar?
Flour is light and full of air, while sugar crystals pack tightly. The same cup holds about 120 g of all-purpose flour but 200 g of granulated sugar, so you must choose the right ingredient.
How should I measure flour for these numbers?
Spoon the flour into the cup and level it with a knife. Scooping straight from the bag packs it down and can add 20 to 30 grams per cup, which is why weighing is more accurate.
What is the difference between a US cup and a metric cup?
A US cup is about 236.6 mL and a metric cup, used in Australia, New Zealand, and Canada, is 250 mL, so a metric cup holds about 6% more of every ingredient.
How many grams is a stick of butter?
A US stick of butter is half a cup, about 113 grams or 4 ounces. Choose Butter and enter 0.5 cups to see it.
Are the weights exact?
They are typical values used by bakers and recipe developers. Real weights vary a few percent with brand, humidity, and how the cup is filled, so treat them as a reliable guide.
