How to convert grams to cups

A gram is a unit of weight and a cup is a unit of volume, so there is no single grams-to-cups number. You need the weight of one cup of the ingredient in front of you, and then you divide:

cups = grams ÷ grams per cup

Take 300 g of granulated sugar. USDA FoodData Central puts a cup of granulated sugar at 200 g, so 300 ÷ 200 = 1.5, which is 1 ½ cups (1.5). The same 300 g of all-purpose flour is 300 ÷ 125 = 2.4, or ≈ 2 ⅜ cups (2.4). Cocoa powder, at 86 g a cup, comes to ≈ 3 ½ cups (3.49). Same weight, three very different scoops, which is why the calculator asks for the ingredient before it gives an answer.

Going the other way, multiply: grams = cups × grams per cup. Switch the calculator to Cups → Grams and it does this for you, including mixed numbers such as 1 1/2.

Grams to cups for baking

Baking recipes written in grams are more reliable than cup recipes, but most American kitchens still measure with cups and spoons. A few habits keep a converted recipe close to what the author made:

Spoon flour, don't scoop it. Spoon it into the cup and level the top with a knife. King Arthur Baking says a compressed cup of all-purpose flour can hold up to 160 g; fluffed and leveled it holds about 120 g. More in how many grams in a cup of flour.
Pack brown sugar. It is the one dry ingredient you press down. Our 220 g figure is for a packed cup; USDA weighs an unpacked cup at 145 g.
Count butter in sticks. A US stick is ½ cup, and USDA weighs it at 113 g.
Use tablespoons for small amounts. For anything under ¼ cup, the tablespoon figure in the result is easier to measure than a fraction of a cup.
Keep the scale if you have one. Converting a gram recipe to cups adds measuring error back in. Convert only when you have to.

Which cup is your recipe using?

Three cup sizes show up in recipes. The US customary cup (236.588 ml) is what American measuring cups hold. The US legal cup (240 ml) is the one on nutrition labels. The metric cup (250 ml) is used in Australian, New Zealand and Canadian recipes. A metric cup holds 5.7% more than a US cup, enough to notice in a cake or a batch of cookies. If a recipe comes from an Australian site, switch the calculator to Metric before you convert.

Grams to cups FAQ

How many cups is 100 grams?

It depends on the ingredient. 100 g of all-purpose flour is ≈ ¾ cup (0.8). 100 g of granulated sugar is ½ cup (0.5). 100 g of butter is ≈ ½ cup (0.44), a bit less than one US stick (113 g). For anything else, type 100 into the calculator above and pick your ingredient.

Is 1 cup always 250 grams?

No. 250 is the volume of a metric cup in millilitres, not a weight. A US cup of water weighs 237 g, and a metric cup of water about 250 g. Dry ingredients weigh much less: a US cup of all-purpose flour is 125 g.

Why is your cup of flour 125 g when some recipes say 120 g?

Cooking Measure uses 125 g per cup of all-purpose flour (USDA FoodData Central) by default; for a King Arthur Baking recipe, use 120 g, about 4% less. The two sources publish different figures and neither is wrong; 120 g vs 125 g flour covers where the gap comes from.

Should I pick the US, US legal, or metric cup?

Use the US cup for American recipes, the metric cup (250 ml) for Australian, New Zealand or Canadian recipes, and the US legal cup (240 ml) only when you are working from a nutrition label.

Can I convert grams to cups without knowing the ingredient?

Not accurately. A cup is a volume, so its weight changes with what is in it. 300 g is ≈ 3 ½ cups (3.49) of cocoa powder but 1 ½ cups (1.5) of granulated sugar.
