Grams to Cups Converter (Cooking Measurements)
To convert grams to cups, divide the grams by the weight of one cup of that ingredient. King Arthur Baking lists all-purpose flour at 120 g per US cup, so 200 g ÷ 120 = 1.67, or about 1⅔ cups. Granulated sugar is heavier at 198 g per cup, so 200 g of sugar is just over 1 cup.
Show steps
- Find the weight of one cup of all-purpose flour. King Arthur Baking lists 1 cup = 120 g.
- Divide the grams by the grams per cup: 200 ÷ 120 = 1.67 US cups.
- Turn the decimal into cups and spoons you can measure: 1.67 cups ≈ 1⅔ cups (1 cup = 16 tbsp = 48 tsp).
- Answer: 200 g all-purpose flour ≈ 1⅔ cups (1.67 US cups, 394 mL). Weights by volume are averages, so treat them as a close guide rather than an exact figure.
How to use the grams to cups converter
- On Grams ↔ cups, pick the ingredient, type the amount and choose its unit. Grams, ounces and pounds give cups and spoons; cups, tablespoons, teaspoons and milliliters give grams.
- Choose US cup or Metric cup to match your recipe.
- Read the answer as a measure you can use, such as “¾ cup + 1 tbsp + 1 tsp”, plus the decimal, the formula and the source figure.
- Use Volume and Weight for plain unit changes, Scale recipe to multiply a whole ingredient list, and Butter for sticks.
Why grams to cups depends on the ingredient
A gram measures weight and a cup measures volume. How much fits in a cup depends on the ingredient’s density: a cup of flour is light and airy, a cup of sugar is packed with fine crystals, and a cup of honey is heavier still. Using King Arthur Baking’s figures, one US cup holds about 120 g of all-purpose flour, 198 g of granulated sugar and 336 g of honey (21 g per tablespoon × 16). That is why no single “grams per cup” number works for every recipe.
Grams to cups formula
cups = grams ÷ grams per cup
grams = cups × grams per cup
For spoons, divide the grams per cup by 16 to get grams per tablespoon, and by 48 to get grams per teaspoon, because 1 cup = 16 tablespoons = 48 teaspoons.
Worked examples
Example 1: 250 g of butter in cups
A US stick of butter is 4 oz, or 113.4 g, and a cup is 2 sticks (226.8 g). 250 ÷ 226.8 = 1.10 cups, which you can measure as 1 cup + 1 tbsp + 2 tsp. That is also about 2.2 sticks.
Example 2: 1½ cups of packed brown sugar in grams
Packed brown sugar is 213 g per cup. 1.5 × 213 = 319.5, so about 320 g.
Example 3: 500 mL of milk in cups and grams
One US cup is 236.59 mL, so 500 ÷ 236.59 = 2.11 cups. King Arthur lists milk at 227 g per cup, so 2.11 × 227 ≈ 480 g.
Grams per cup chart
All weights are from the King Arthur Baking ingredient weight chart, for dry ingredients spooned into the cup and leveled. Where the chart gives a smaller measure (for example honey per tablespoon or cornstarch per ¼ cup), the cup figure is scaled up from it.
| Ingredient | 1 US cup | 1 tbsp | 100 g is about |
|---|---|---|---|
| All-purpose or bread flour | 120 g | 7.5 g | ¾ cup + 1 tbsp + 1 tsp |
| Whole wheat flour | 113 g | 7.1 g | ¾ cup + 2 tbsp + ½ tsp |
| Almond flour | 96 g | 6 g | 1 cup + 2 tsp |
| Cornstarch | 112 g | 7 g | ¾ cup + 2 tbsp + ¾ tsp |
| Granulated sugar | 198 g | 12.4 g | ½ cup |
| Brown sugar, packed | 213 g | 13.3 g | ⅓ cup + 2 tbsp + ½ tsp |
| Confectioners’ sugar | 113 g | 7.1 g | ¾ cup + 2 tbsp + ½ tsp |
| Honey | 336 g | 21 g | ¼ cup + 2¼ tsp |
| Maple syrup | 312 g | 19.5 g | ¼ cup + 1 tbsp + ½ tsp |
| Butter | 227 g | 14.2 g | ⅓ cup + 1 tbsp + 2¼ tsp |
| Vegetable oil | 198 g | 12.4 g | ½ cup |
| Milk, water or heavy cream | 227 g | 14.2 g | ⅓ cup + 1 tbsp + 2¼ tsp |
| Cocoa powder | 84 g | 5.3 g | 1 cup + 3 tbsp + ¼ tsp |
| Rolled oats | 89 g | 5.6 g | 1 cup + 2 tbsp |
| Chocolate chips | 170 g | 10.6 g | ½ cup + 1 tbsp + 1¼ tsp |
| Chopped walnuts | 113 g | 7.1 g | ¾ cup + 2 tbsp + ½ tsp |
| Table salt | 288 g | 18 g | ⅓ cup + ⅝ tsp |
The converter covers 40 ingredients, including semolina, cornmeal, superfine sugar, molasses, olive and coconut oil, sour cream, yogurt, cream cheese, cheeses, rice, raisins, peanut butter, coconut, baking powder, baking soda and instant yeast. King Arthur lists water and other thin liquids at 8 oz (227 g) per cup, a rounded kitchen figure.
US cup vs metric cup
A US customary cup is exactly 236.5882365 mL (NIST lists it as 236.5882 mL), because it is 1/16 of the US gallon of 231 cubic inches. A metric cup, used in many recipes written outside the US, is 250 mL, about 5.7% bigger. US nutrition labels use a third value: the FDA rounds 1 cup to 240 mL, 1 tablespoon to 15 mL and 1 teaspoon to 5 mL for labeling.
| US unit | Equals | Milliliters (exact, rounded) |
|---|---|---|
| 1 teaspoon | ⅓ tablespoon | 4.93 mL |
| 1 tablespoon | 3 teaspoons | 14.79 mL |
| 1 fluid ounce | 2 tablespoons | 29.57 mL |
| 1 cup | 16 tablespoons = 8 fl oz | 236.59 mL |
| 1 pint | 2 cups | 473.18 mL |
| 1 quart | 4 cups | 946.35 mL |
Ounces to grams
One ounce of weight is exactly 28.349523125 g, so 8 oz = 226.8 g and 1 pound (16 oz) = 453.59 g. A fluid ounce is a different unit: it measures volume (29.57 mL). They only line up for water-like liquids, so a recipe that says “8 ounces of flour” means weight, not a cup.
Butter sticks to grams and cups
| Butter | Cups | Tablespoons | Grams | Ounces |
|---|---|---|---|---|
| ½ stick | ¼ | 4 | 57 | 2 |
| 1 stick | ½ | 8 | 113 | 4 |
| 2 sticks | 1 | 16 | 227 | 8 |
| 4 sticks (1 lb) | 2 | 32 | 454 | 16 |
| 250 g block | 1.1 | 17.6 | 250 | 8.8 |
Scaling a recipe up or down
Divide the servings you want by the servings the recipe makes to get the scale factor, then multiply every amount by it. For 4 servings to 6, the factor is 6 ÷ 4 = 1.5, so 1½ cups of flour becomes 2¼ cups and 1¼ cups of milk becomes 1⅞ cups, which you measure as 1¾ cups + 2 tbsp. The Scale recipe tab does this for a whole list and rounds to cup and spoon sizes you own. Pan size and baking time do not scale in a straight line, so check doneness early.
Why your cups may weigh more or less
- Packing. King Arthur notes that a densely packed cup can hold up to 160 g of all-purpose flour, against 120 g when you fluff the flour, sprinkle it into the cup and level it. That is a third more flour.
- Brown sugar is measured packed firmly; most other dry ingredients are spooned and leveled.
- Chopped, grated or shredded foods settle differently from batch to batch.
- Different charts use different figures. A converter that lists flour at 125 g per cup will give slightly fewer cups than one that uses 120 g.
For baking, a kitchen scale removes all of this guesswork.

Multiply cups by grams per cup: 0.75 × 198 = 148.5, so about 149 g. 264 g comes from dividing instead of multiplying.
1 cup = 16 tablespoons, and each tablespoon is 3 teaspoons, so a cup is also 48 teaspoons.
The US cup is 1/16 of a 3,785.411784 mL gallon: 236.59 mL. 240 mL is the rounded nutrition-label cup and 250 mL is a metric cup.
One US stick is 4 oz = 113.4 g, so 2 sticks = 226.8 g, about 227 g. That is also 1 cup.
A gram is always the same weight. Flour is lighter per cup (120 g) than sugar (198 g), so 100 g of flour needs more volume.
1 oz = 28.349523125 g, so 8 × 28.35 = 226.8 g. 236.6 is the number of milliliters in 8 fluid ounces, a volume.
½ cup = 8 tablespoons, so 8 × 21 = 168 g. A full cup (16 tbsp) would be 336 g.
The extra is 160 − 120 = 40 g, and 40 ÷ 120 ≈ 0.33, or about 33% more. 25% comes from dividing by 160 instead of 120.

Frequently asked questions
How many cups is 100 grams of flour?
About ¾ cup + 1 tbsp + 1 tsp of all-purpose flour, or 0.83 cup, using 120 g per cup. If you scoop straight from the bag, the same 100 g fills less of the cup.
How many grams are in a cup of sugar?
About 198 g of granulated sugar, 213 g of packed brown sugar and 113 g of confectioners' sugar per US cup, per King Arthur Baking.
Is a cup 240 mL or 250 mL?
Neither exactly. A US customary cup is 236.59 mL. Nutrition labels round it to 240 mL, and a metric cup is 250 mL. Choose the cup size in the converter that matches your recipe.
How many grams is a stick of butter?
A US stick is 4 oz, which is 113 g, and it equals ½ cup or 8 tablespoons. Two sticks make 1 cup (227 g).
Why do grams to cups converters give different answers?
They use different grams-per-cup figures and measuring methods. This page uses one named source, King Arthur Baking, for every ingredient and shows the figure it used.
