How Many Cups Is 100 Grams?
100 g of granulated sugar = exactly ½ cup.
100 g of all-purpose flour ≈ ¾ cup (0.80 cup) · 100 g of butter ≈ 7 tablespoons (just under ½ cup). Every ingredient is different — see the full table below.
100 grams is one of the most satisfying weights in metric baking — sugar hits an exact half cup, flour is just under a full cup, and butter is a hair under half. But each of those answers is different, because a cup is a fixed volume while a gram is a fixed weight. The table below shows exactly where 100 g lands for every common baking ingredient.
100g to Cups by Ingredient
| Ingredient | 100 g = | Cup Equivalent |
|---|---|---|
| All-purpose flour | 0.80 cup | ¾ cup + 1 tbsp |
| Bread flour | 0.79 cup | ¾ cup + 1 tsp |
| Cake flour | 0.88 cup | ¾ cup + 2 tbsp |
| Whole wheat flour | 0.77 cup | ¾ cup |
| Almond flour | 1.04 cup | 1 cup + 1 tsp |
| Granulated sugar | 0.50 cup | Exactly ½ cup |
| Brown sugar (packed) | 0.45 cup | Scant ½ cup |
| Powdered sugar | 0.83 cup | ¾ cup + 2 tbsp |
| Butter | 0.44 cup | 7 tablespoons |
| Olive oil | 0.46 cup | Scant ½ cup |
| Cocoa powder | 1.18 cup | 1 cup + 3 tbsp |
| Rolled oats | 1.11 cup | 1 cup + 2 tbsp |
| Cornstarch | 0.78 cup | ¾ cup |
| Chocolate chips | 0.59 cup | ½ cup + 1 tbsp |
| Peanut butter | 0.39 cup | ⅓ cup + 1 tbsp |
| Honey | 0.29 cup | ¼ cup + 1 tsp |
| Maple syrup | 0.32 cup | ⅓ cup |
| Milk (whole) | 0.41 cup | ⅓ cup + 1 tbsp |
Values use the spoon-and-level method. 1 US cup = 236.6 ml = 16 tablespoons.
Why Sugar Hits Exactly ½ Cup at 100g
Granulated sugar is one of the few ingredients where the US standard cup weight is a round number: 200 g per cup. That means 100 g lands cleanly at ½ cup — no rounding needed. Brown sugar packs tighter (220 g per cup, so 100 g = 0.45 cup), and powdered sugar is lighter (120 g per cup, so 100 g = 0.83 cup). Only granulated sugar gives you the neat half-cup mark.
100g of Flour: Why It Falls Short of 1 Cup
Standard all-purpose flour weighs about 125 g per cup when spooned and leveled. So 100 g is 100/125 = 0.80 cup, or roughly ¾ cup plus a tablespoon. Many bakers instinctively reach for 1 cup when they see 100 g, and end up 25% over. This is one of the most common cause of dense, dry baked goods.
Cake flour is lighter (114 g per cup), so 100 g gets closer to 1 cup (0.88 cup). Whole wheat flour is denser (130 g per cup), landing at 0.77 cup for 100 g.

FAQ
How many cups is 100g of flour?
100 g of all-purpose flour is about 0.80 cup — just under a full cup (technically ¾ cup plus about 1 tablespoon). Cake flour is lighter and reaches 0.88 cup for the same 100 g; bread flour is slightly denser at 0.79 cup.
Is 100g of sugar exactly ½ cup?
Yes — granulated sugar is the one ingredient where 100 g lands on a clean fraction. The US baking standard is 200 g per cup, so 100 g = exactly ½ cup. Brown sugar packs tighter (0.45 cup) and powdered sugar is lighter (0.83 cup), so only granulated sugar hits the exact mark.
How many cups is 100g of butter?
About 7 tablespoons, or 0.44 cup (just under ½ cup). Butter is denser than most people expect: a full cup of butter weighs 227 g, so 100 g is roughly 44% of a cup. You can also think of it as slightly more than half a US stick (1 stick = 113 g = ½ cup).
How many cups is 100g of cocoa powder?
About 1.18 cups — just over 1 cup plus 3 tablespoons. Cocoa powder is very light and airy (about 85 g per cup), so 100 g actually exceeds a full measuring cup. This is why chocolate cakes can look like a lot of cocoa: the gram weight is compact.
How many tablespoons is 100g?
Multiply the cup value by 16. For flour (0.80 cup) that's about 12.8 tbsp; for sugar (0.50 cup) = 8 tbsp exactly; for butter (0.44 cup) = 7 tbsp; for cocoa (1.18 cup) = about 18.8 tbsp. The full tablespoon count always depends on the ingredient's density.
Is 100g more accurate than 1 cup for baking?
Yes — significantly. The same measuring cup can hold anywhere from 120 g to 150 g of flour depending on how you fill it (scoop vs. spoon-and-level). A scale set to 100 g removes that variability entirely. For anything where precision matters (macarons, sourdough, layered cakes), grams always win.
