Grams to Cups (g to cup)
Convert g to cup instantly — cups = grams ÷ (236.588 × density). Cups measure volume while grams measure weight, so the answer depends on the ingredient's density — flour packs differently than sugar or butter. Pick your ingredient above for an exact answer.

How to convert g to cup
The conversion formula is cups = grams ÷ (236.588 × density). Cups measure volume while grams measure weight, so the answer depends on the ingredient's density — flour packs differently than sugar or butter. Pick your ingredient above for an exact answer.
For a rough mental estimate: 1 US cup of all-purpose flour weighs about 125 g, granulated sugar about 200 g, and water exactly 237 g. If a recipe gives you grams but you measure with cups, always convert with the right ingredient — substituting one for another is the most common baking mistake.
Going the other way? See the cups to grams converter, which uses the reciprocal relationship.
Worked examples
Example: convert 100 g to cup. Apply the formula — cups = grams ÷ (236.588 × density) — and you get 0.799 cup. Reverse-check it by using the cups to grams to come back to 100 g; if you do not land on the original number, a factor was inverted.
Example: convert 500 g to cup. Apply the formula — cups = grams ÷ (236.588 × density) — and you get 4 cup. Reverse-check it by using the cups to grams to come back to 500 g; if you do not land on the original number, a factor was inverted.
Where the factor comes from
Baking references converged on a set of standard cup weights decades ago: King Arthur and King Arthur-style charts, USDA food data, and cookbooks like On Food and Cooking all agree within a few grams. Our density values are averages of those references, expressed in grams per milliliter, and they match what professional bakers weigh on a scale. If precision matters — macarons, sourdough hydration, custards — weigh instead of scoop.Common mistakes
One density for everything. The most common baking failure: converting grams to cups with a water factor. 200 g of flour is about 1.6 cups, not 0.85 — a 90% error that ruins the bake.
Sifting changes the weight. Sifted flour is roughly 15–20% lighter by volume than scooped. Charts assume the measuring style stated — ours assumes the standard spoon-and-level method.
Trusting "a cup is a cup". Even among flours, cup weights range from 114 g (cake) to 132 g (bread). Pick the exact ingredient in the converter above.
Quick mental shortcuts
Mental shortcuts: grams of flour → cups ≈ ÷125; sugar ≈ ÷200; butter ≈ ÷227 per cup (1 stick = 113 g = ½ cup). Water, milk and stock: 1 g = 1 ml exactly.

FAQ
How many cups is 100 g?
It depends on the ingredient. For all-purpose flour, 100 g is about 0.8 cup; for granulated sugar about 0.5 cup; for water or milk, 0.42 cup. Pick your ingredient in the converter for an exact answer.
Why does g-to-cup conversion depend on the ingredient?
Grams measure weight (mass) while cups measure volume. Cups measure volume while grams measure weight, so the answer depends on the ingredient's density — flour packs differently than sugar or butter. Pick your ingredient above for an exact answer.
What is 125 g of flour in cups?
125 g of all-purpose flour is about 1 cup; bread flour is slightly denser at 132 g per cup, cake flour lighter at 114 g. Select any ingredient above for its exact value.
Is a cup the same worldwide?
No. A US legal cup is 236.588 ml (what US recipes use). Australia, Canada and most metric countries use a 250 ml cup — about 5.7% larger. This converter uses the US cup; scale recipes accordingly if your source uses metric cups.
