Grams to cups converter.
Accurate, density-based cooking and baking conversions. Because 100 grams of flour, sugar, and butter fill a cup completely differently.
One weight, five very different cups.
Every cup below holds the exact same 210 grams. Oats fills more than two full cups, while dense honey fills barely over half a cup. The dashed line marks the standard 1-cup level.

Understanding grams to cups conversion.
Why there isn't one universal formula.
Grams measure weight (mass), while cups measure volume (space). A cup of flour, sugar, butter, and water all weigh drastically different amounts because each ingredient has a distinct physical density. That is why accurate cooking and baking conversions always start with the specific ingredient.
- 1 cup All-Purpose Flour = 125 grams
- 1 cup Granulated Sugar = 200 grams
- 1 cup Butter = 227 grams
- 1 cup Water = 236.59 grams
Why precise measurements matter in baking.
Baking is chemistry. Recipes depend on precise moisture-to-protein and fat-to-sugar ratios. Too much flour can turn tender cakes dense and dry, while inaccurate sugar or liquid amounts ruin cookie spread and rise.
Practical Measuring Tips
- Use a digital kitchen scale whenever possible.
- Spoon flour into cups and level off instead of scooping.
- Pack brown sugar only when the recipe specifically requests it.
- Use liquid measuring cups for water, milk, and cooking oils.
- Ensure your recipe matches US customary cup standards (236.59 ml).
Common measuring mistakes to avoid.
Applying a single generic multiplier across completely different ingredients.
Failing to pack brown sugar or mistakenly packing flour into the cup.
Confusing US Customary (236.59ml) with Australian/Metric cups (250ml).
Assuming sifted and unsifted powders have identical density per cup.

How many grams to a cup?
There is no single universal answer because grams measure weight and cups measure volume. A cup of granulated sugar weighs 200 grams, all-purpose flour weighs 125 grams, butter weighs 227 grams, and water weighs 236.59 grams. To convert grams to a cup accurately, you must know the specific ingredient's density.
1 cup is equal to how many grams?
One standard US Customary cup holds 236.59 milliliters. In grams, 1 cup equals: 125g of all-purpose flour, 200g of granulated sugar, 220g of packed brown sugar, 227g of butter, 85g of cocoa powder, 90g of rolled oats, 340g of honey, or 237g of water.
How many grams to a cup of flour?
One cup of all-purpose flour equals approximately 125 grams when measured using the standard 'spoon-and-level' method. If scooped directly from the bag, flour compresses and can weigh up to 150 grams, which often ruins delicate baked goods. Bread flour weighs about 136g per cup, while cake flour weighs about 114g per cup.
150 grams is equal to how many cups?
150 grams converts to different cup amounts depending on the ingredient: 150g of all-purpose flour equals approximately 1.2 cups (1 ⅕ cups); 150g of granulated sugar equals 0.75 cups (¾ cup); 150g of butter equals 0.66 cups (⅔ cup or 10.6 tbsp); and 150g of rolled oats equals 1.67 cups (1 ⅔ cups).
How to measure grams in cups?
To measure grams in cups without a scale: divide the recipe's weight in grams by the ingredient's density in grams per cup (Formula: Cups = Grams ÷ Ingredient Density). For example, 100 grams of flour ÷ 125 g/cup = 0.8 cups (approximately 13 tablespoons, or just over ¾ cup).
How to measure 100 grams in cups?
For all-purpose flour, 100 grams equals approximately 0.8 cups (just under 13 tablespoons). For granulated white sugar, 100 grams equals exactly 0.5 cups (½ cup). For butter, 100 grams is 0.44 cups (approx 7 tablespoons or just under 1 stick). For water or milk, 100 grams is approximately 0.42 cups.
200 grams is equal to how many cups?
200 grams of granulated white sugar equals exactly 1 US cup. For all-purpose flour, 200 grams equals 1.6 cups (approximately 1 ⅔ cups). For butter, 200 grams equals 0.88 cups (about 14 tablespoons). For rolled oats, 200 grams equals 2.22 cups (about 2 ¼ cups).
How to convert cups to grams?
To convert cups to grams, multiply the number of cups by the ingredient's gram weight per cup (Formula: Grams = Cups × Density). For example, 2 cups of sugar × 200 grams/cup = 400 grams. 1.5 cups of flour × 125 grams/cup = 187.5 grams.
How many cups to grams?
Converting cups to grams requires multiplying the cup measurement by the ingredient's density. For quick reference: 1 cup flour = 125g; ½ cup flour = 62.5g; 1 cup sugar = 200g; ½ cup sugar = 100g; 1 cup butter = 227g (2 sticks); ½ cup butter = 113.5g (1 stick).
How to change grams into cups?
To change grams into cups: 1) Identify the ingredient from our database to find its grams-per-cup density. 2) Divide your target gram amount by that density figure. 3) Use dry measuring cups for solids and powders (spooning and leveling), and liquid measuring cups for fluids at eye level.
