How Many Cups Is 400 Grams?
400 g of granulated sugar = exactly 2 cups.
400 g of flour ≈ 3 cups + 3 tbsp · 400 g of butter ≈ 1¾ cups + 2 tbsp. Full table for all common baking ingredients below.
400 grams doubles the 200-gram cup standard for sugar — landing at a clean 2 cups with no approximation. It is a large baking quantity: enough flour for a 4-cup loaf, enough sugar to sweeten a layer cake, or enough butter for rich shortbread. The table below shows the exact cup amount for every common baking ingredient at 400 g.
400g to Cups by Ingredient
| Ingredient | 400 g = | Cup Equivalent |
|---|---|---|
| All-purpose flour | 3.20 cups | 3 cups + 3 tbsp + 1 tsp |
| Bread flour | 3.15 cups | 3 cups + 2 tbsp + 1 tsp |
| Cake flour | 3.51 cups | 3½ cups |
| Whole wheat flour | 3.08 cups | 3 cups + 1 tbsp |
| Almond flour | 4.17 cups | 4 cups + 2¾ tbsp |
| Granulated sugar | 2.00 cups | Exactly 2 cups |
| Brown sugar (packed) | 1.82 cups | 1¾ cups + 1 tbsp |
| Powdered sugar | 3.33 cups | 3⅓ cups |
| Butter | 1.76 cups | 1¾ cups + 2 tbsp |
| Olive oil | 1.85 cups | 1¾ cups + 1 tbsp + 1 tsp |
| Cocoa powder | 4.71 cups | 4¾ cups |
| Rolled oats | 4.44 cups | 4 cups + 7 tbsp |
| Cornstarch | 3.13 cups | 3 cups + 2 tbsp |
| Chocolate chips | 2.35 cups | 2⅓ cups |
| Peanut butter | 1.55 cups | 1½ cups + 1 tbsp |
| Honey | 1.18 cups | 1 cup + 3 tbsp |
| Maple syrup | 1.29 cups | 1 cup + 4½ tbsp |
| Milk (whole) | 1.64 cups | 1½ cups + 2 tbsp |
Values use the spoon-and-level method. 1 US cup = 16 tablespoons.
Why 400g Sugar = 2 Cups, But 400g Flour ≠ 2 Cups
Sugar and flour look similar in a recipe, but they weigh very differently per cup:
- Sugar: 200 g per cup → 400 g = exactly 2 cups.
- Flour: 125 g per cup → 400 g = 3.2 cups — 60% more volume than sugar.
This gap exists because flour is a light, airy powder while sugar is dense, heavy granules. Never assume two ingredients occupy the same cup volume for the same gram weight.

FAQ
Is 400g of sugar exactly 2 cups?
Yes. Granulated sugar is 200 g per US cup, so 400 g = 400/200 = 2.00 cups exactly. No rounding, no approximation. This clean doubling makes 400 g a convenient weight in recipes that were originally written in US cups — 2 cups of sugar translates directly to 400 g.
How many cups is 400g of flour?
400 g of all-purpose flour is 3.20 cups — 3 cups plus 3 tablespoons + 1 teaspoon. Flour weighs 125 g per cup, so 400/125 = 3.2. Cake flour is lighter (3.51 cups for 400 g); whole wheat flour is denser (3.08 cups). For bread baking, always weigh 400 g — the small differences between flour types make measuring in cups unreliable at this quantity.
How many cups is 400g of butter?
400 g of butter is 1.76 cups — 1¾ cups plus about 2 tablespoons. Butter is 227 g per cup. In US stick terms, 400 g is approximately 3½ sticks (each stick = 113 g = ½ cup). This amount of butter appears in large batches of shortbread, croissant dough, or buttercream frosting.
How many cups is 400g of oats?
400 g of rolled oats is 4.44 cups — just under 4½ cups. Oats weigh about 90 g per cup. This is a large amount of oats, enough for a double batch of granola or several dozen oat cookies.
How many tablespoons is 400g?
Multiply the cup value by 16. Granulated sugar (2.00 cups) = 32 tablespoons exactly. Flour (3.20 cups) = 51.2 tbsp. Butter (1.76 cups) = 28 tbsp. Cocoa (4.71 cups) = 75 tbsp. Tablespoon counts at 400 g are large — a scale is much more practical at this volume.
Is 400g close to 1 lb?
Almost — 400 g = 14.11 oz = 0.88 lb. One pound = 454 g, so 400 g is about 88% of a pound. If a recipe calls for 'almost a pound' of an ingredient, 400 g is a reasonable metric approximation.
