How to Convert Cups to Grams
Cups measure volume while grams measure weight. To convert, multiply the cup measurement by the cup volume in mL (236.588) and by the ingredient's density:
Example: 1 cup of water (density 1.00 g/mL)
= 1 Γ 236.588 Γ 1.00 = 236.6 grams
Example: 1 cup of all-purpose flour (density 0.53 g/mL)
= 1 Γ 236.588 Γ 0.53 = 125.4 grams
Example: 1 cup of granulated sugar (density 0.85 g/mL)
= 1 Γ 236.588 Γ 0.85 = 201.1 grams

| Ingredient | Density | ΒΌ cup | Β½ cup | 1 cup |
|---|---|---|---|---|
| All-Purpose Flour | 0.53 g/mL | 31 g | 63 g | 125 g |
| Granulated Sugar | 0.85 g/mL | 50 g | 101 g | 201 g |
| Brown Sugar (packed) | 0.93 g/mL | 55 g | 110 g | 220 g |
| Powdered Sugar | 0.56 g/mL | 33 g | 66 g | 132 g |
| Butter | 0.91 g/mL | 54 g | 108 g | 215 g |
| Whole Milk | 1.03 g/mL | 61 g | 122 g | 244 g |
| Olive Oil | 0.91 g/mL | 54 g | 108 g | 215 g |
| Honey | 1.43 g/mL | 85 g | 169 g | 338 g |
| Rice (uncooked) | 0.82 g/mL | 49 g | 97 g | 194 g |
| Oats (rolled) | 0.34 g/mL | 20 g | 40 g | 80 g |
Key insight: 1 cup of flour (125g) and 1 cup of sugar (201g) are very different weights β this is exactly why professional bakers weigh ingredients in grams.
Why Cup Measures Vary by Ingredient
A cup is a volume measurement β it always holds exactly 236.588 mL of space. But different ingredients fill that space differently:
- Flour is fluffy with lots of air β 1 cup = only 125g
- Sugar is denser, granules pack tighter β 1 cup = 201g
- Honey is a thick liquid β 1 cup = 338g
- Oats are very airy β 1 cup = only 80g
This is why "1 cup" can mean anything from 80g to 338g depending on the ingredient.
Scooping vs. Weighing β Why Grams Win
How you scoop flour into a cup drastically changes the weight:
| Method | 1 Cup of Flour | Difference |
|---|---|---|
| Spoon-and-level (standard) | ~125 g | Baseline |
| Scoop directly from bag | ~140β160 g | +12% to +28% |
| Sifted, then spooned | ~110β115 g | -8% to -12% |
| Kitchen scale (grams) | Exactly 125 g | 0% error |
That 28% difference between scooping and spoon-leveling can mean the difference between a light, fluffy cake and a dense brick. This is the #1 reason why bakers recommend weighing ingredients.
US Cup vs. Metric Cup vs. Imperial Cup
| Cup Standard | Volume | Where Used |
|---|---|---|
| US Customary Cup | 236.588 mL (8 US fl oz) | United States |
| Metric Cup | 250 mL | Australia, Canada, NZ |
| Imperial Cup | 284.131 mL (10 imp fl oz) | UK (historical) |
| Japanese Cup | 200 mL | Japan |
When following a recipe, always check which "cup" is intended. A metric cup is 5.7% larger than a US cup.
What Is a Cup?
A US customary cup is a unit of volume equal to 236.588 mL, 8 US fluid ounces, 16 tablespoons, or 48 teaspoons. It is the standard volume measure used in American home cooking and baking recipes.
What Is a Gram?
A gram (g) is a metric unit of mass equal to 1/1,000 of a kilogram or approximately 0.035 ounces. In baking, grams are the preferred measurement because they are precise and not affected by how you scoop or level your ingredients.
