Guides /Grams & Cups
Cups to grams:
common ingredients.
A single reference table for the 20 most common baking ingredients — gram equivalents for 1 cup, ½ cup, ¼ cup, and ⅓ cup.

|---|---|---|---|---|
| All-purpose flour (spoon & level) | 120 | 60 | 30 | 40 |
| Bread flour | 127 | 64 | 32 | 42 |
| Cake flour | 100 | 50 | 25 | 33 |
| Whole wheat flour | 128 | 64 | 32 | 43 |
| Granulated sugar | 200 | 100 | 50 | 67 |
| Brown sugar (packed) | 213 | 107 | 53 | 71 |
| Powdered sugar (sifted) | 113 | 57 | 28 | 38 |
| Butter | 227 | 113 | 57 | 76 |
| Honey / maple syrup | 340 | 170 | 85 | 113 |
| Milk (whole) | 244 | 122 | 61 | 81 |
| Heavy / whipping cream | 238 | 119 | 60 | 79 |
| Vegetable oil | 218 | 109 | 55 | 73 |

| Breadcrumbs (dry) | 108 | 54 | 27 | 36 |

| Baking powder | 230 | 115 | 58 | 77 |
| Cornstarch | 120 | 60 | 30 | 40 |
All values are for US cups (240 ml). Flour values assume spoon-and-level technique.
Why grams beat cups in baking
Volume measures are affected by how densely an ingredient sits in the cup — how it was stored, whether it settled during shipping, how you scooped it. Grams aren't. A professional pastry chef using 240 g of flour will get the same result every time; a home baker using "2 cups" might get anything from 220 to 300 g depending on technique. For anything where texture matters — bread, cakes, pastry — weighing by grams removes the biggest variable.
Liquids: cups to grams vs cups to ml
For liquids near water density (milk, cream, most stocks), 1 cup ≈ 240 ml ≈ 240 g. For denser liquids like honey (340 g/cup) or lighter ones like oil (218 g/cup), the difference is significant. If your recipe is in cups and you're weighing, use the ingredient-specific values above rather than assuming 1 cup = 240 g.
The scoop-and-level vs spoon-and-level gap
All-purpose flour values in the table above assume the spoon-and-level technique: use a separate spoon to fill the cup, then sweep a straight edge across the top. If you instead dip the cup directly into the flour bag and scoop it out, you pack the flour and can easily end up with 150–160 g instead of 120 g per cup. That 30% variation is why two bakers following the same cup-based recipe can produce noticeably different results. Switching to grams eliminates the technique variable entirely — 120 g is 120 g regardless of how you get it onto the scale.
Converting a cup recipe to weight for future use
Once you've made a recipe successfully, it's worth annotating the cup measurements with the gram values from this chart — or by weighing each ingredient as you add it. You'll end up with a reliable gram version of the recipe that you can reproduce exactly every time, share with bakers in metric countries, and scale up or down without worrying about fractional cup measures. Write the gram values in pencil in the cookbook margin, or add a note to your digital recipe app. The one-time conversion pays dividends on every future bake.
Frequently asked questions
- How many grams is 1 cup of all-purpose flour?
- 1 cup of all-purpose flour weighs 120 g when measured using the spoon-and-level method. If you scoop the cup directly into the flour bag, it can pack to 150 g or more.
- How many grams is 1 cup of sugar?
- 1 cup of granulated white sugar weighs 200 g. Brown sugar packed firmly weighs about 213 g per cup; loosely piled it's closer to 170 g.
- Why do grams give more accurate results than cups?
- Grams measure mass, which doesn't vary with how you fill a container. A cup of flour can weigh anywhere from 120 to 150 g depending on technique — grams eliminate that variable entirely.
- Is 1 cup of liquid the same weight as 1 cup of flour?
- No. 1 cup of water weighs 240 g. 1 cup of all-purpose flour weighs 120 g. Each ingredient has its own density, so you need ingredient-specific values — not a single cups-to-grams factor.
- How do I convert a recipe from cups to grams?
- Find each ingredient in the reference table, note its gram weight per cup, and multiply by your cup amount. Or paste the full ingredient list into Recipe Converter Pro and switch to Metric mode — it applies density-based conversion automatically.
