A recipe in cups and one in grams describe the same food in different languages, and the translation isn’t one-size-fits-all: a cup of flour weighs 125 grams, but a cup of honey weighs 340. That’s why a generic “cups to grams” number is often wrong. This converter uses each ingredient’s real density, so the swap between weight and volume actually matches what the recipe intends.
Pick your ingredient, enter an amount, and convert between cups, tablespoons, grams, ounces and millilitres.

Ingredient density
Volume ↔ weight needs the grams in one US cup of this ingredient
1 cup flour = 125 g = 125 g
- 2
Convert to grams
g = Amount × (cups/unit) × g/cup · for oz, Amount × 28.349523125 (1 tbsp = 1/16 cup, 1 tsp = 1/48 cup, 1 ml = 1/236.5882365 cup)
2 × 1 × 125 = 250 g
- 3
Convert to the target unit
Target = g ÷ g/cup ÷ (cups/unit) · for oz, g ÷ 28.349523125
250 g = 250 g

Good to know: A cup of flour is 125 g but a cup of honey is 340 g — volume measures depend on the ingredient. Packing flour into the cup can push it to 150 g; weigh for precise baking.
Cooking Converter — how it works
Weight ↔ volume needs the ingredient
Grams measure weight; cups measure volume. Converting between them depends on density — how heavy the ingredient is for its size. The tool stores grams-per-cup for common baking staples:
| Ingredient | Grams per cup |
|---|---|
| Flour (all-purpose) | 125 |
| Granulated sugar | 200 |
| Butter | 227 |
| Honey | 340 |
| Milk / water | ~240 |
| Rice (uncooked) | 185 |
Everything is routed through grams: your amount is converted to grams using the ingredient’s density, then to the unit you want.
Volume units are fixed ratios
Between volume units the ratio never changes, whatever the ingredient: 1 cup = 16 tablespoons = 48 teaspoons ≈ 237 ml. Only the weight ↔ volume step depends on the ingredient.
Why weighing wins in baking
Scooping a cup of flour can vary by 20% depending on how it’s packed, which is enough to change a bake. Converting to grams and weighing removes that error — a big reason serious bakers work in grams. Ingredient densities are standard references and can differ slightly by brand and humidity.
Worked example
A recipe calls for 2 cups of all-purpose flour but your scale works in grams. At 125 g per cup, that’s 2 × 125 = 250 g. The same 2 cups of honey would be 2 × 340 = 680 g — nearly three times heavier for the identical volume, which is exactly why the ingredient has to be part of the conversion. Going the other way, 200 g of granulated sugar comes back to precisely 1 cup.
Grams per cup by ingredient
Based on the US cup (240 ml); density varies, so a cup of flour and a cup of honey weigh very differently.
| Ingredient | 1 cup | 1 tbsp | 100 g |
|---|---|---|---|
| All-purpose flour | 125 g | 7.8 g | 0.8 cup |
| Granulated sugar | 200 g | 12.5 g | 0.5 cup |
| Brown sugar (packed) | 220 g | 13.8 g | 0.45 cup |
| Powdered sugar | 120 g | 7.5 g | 0.83 cup |
| Butter | 227 g | 14.2 g | 0.44 cup |
| Milk | 240 g | 15 g | 0.42 cup |
| Water | 237 g | 14.8 g | 0.42 cup |
| Oil | 218 g | 13.6 g | 0.46 cup |
| Honey | 340 g | 21.3 g | 0.29 cup |
| Rice (uncooked) | 185 g | 11.6 g | 0.54 cup |
| Rolled oats | 90 g | 5.6 g | 1.11 cup |
| Cocoa powder | 100 g | 6.3 g | 1 cup |
| Table salt | 273 g | 17.1 g | 0.37 cup |
Frequently asked questions
How many grams are in a cup?+
It depends entirely on the ingredient. A cup of all-purpose flour is about 125 g, granulated sugar 200 g, butter 227 g and honey 340 g. Because density varies so much, you must pick the ingredient — a single “cup to grams” number doesn’t exist.
Why does the ingredient matter for the conversion?+
Grams measure weight and cups measure volume, and different ingredients weigh different amounts for the same volume. A cup of flour and a cup of honey occupy the same space but weigh 125 g and 340 g respectively, so the conversion needs each ingredient’s density.
Is it more accurate to bake by weight?+
Yes. A scooped cup of flour can vary by up to 20% depending on packing, which noticeably affects a bake. Weighing in grams removes that variability, which is why most professional and serious home bakers prefer weight over volume.
How many tablespoons are in a cup?+
Sixteen. A US cup is 16 tablespoons or 48 teaspoons, roughly 237 millilitres. These volume-to-volume ratios are fixed for every ingredient — only the conversion to and from grams depends on what you’re measuring.
Are the ingredient weights exact?+
They’re standard reference densities, accurate enough for cooking and baking, but real values shift a little with brand, grind, humidity and how the ingredient is packed. For most recipes the small variation doesn’t matter; for precision work, use a manufacturer’s stated weight if given.
