> The cups to grams converter turns US cup, tablespoon, teaspoon or millilitre measures into grams for common baking ingredients. Because flour, sugar and butter have different densities, it uses a specific weight per cup for each ingredient.

## Inputs

- Ingredient
- Amount (cups (US), tbsp, tsp, mL)

## Results

- Weight

## Formula

```
grams = cups × grams per cup (ingredient density)
```

## Explanation

Weighing ingredients is the most reliable way to bake. A cup of flour can vary by 20% depending on how it is scooped, while 125 g is always 125 g.

### How to use it

Choose an ingredient, enter the amount and unit. Type a weight into the result to convert grams back to cups.

### How cup weights are defined

Values are typical weights for spooned-and-levelled measures in a US cup (236.6 mL). Packed brown sugar and sifted flour differ, so weigh when precision matters.

### Inputs explained

FieldWhat to enterIngredientChoose one: All-purpose flour, Granulated sugar, Brown sugar (packed), Powdered sugar …AmountUnits: cups (US), tbsp, tsp, mL

### Example values

How the main result changes when **Amount** changes and everything else stays at the example values above:

Amount (cups (US))Weight (g)11251.518822502.531333754500

## Worked example

2 cups of all-purpose flour at 125 g per cup = **250 g**.

## Key terms

- **US cup**: 236.6 mL; a metric cup is 250 mL.
- **Density**: Mass per volume; it differs between ingredients.
- **Spoon and level**: Spooning flour into a cup and scraping it flat, rather than scooping.

## FAQ

**Why does sugar weigh more than flour per cup?**
Sugar crystals pack more densely than flour particles.

**Is a UK cup different?**
Recipes in the UK and Australia often use a 250 mL metric cup.

**Can I convert butter sticks?**
One US stick is half a cup, about 113 g.

**What formula does the Cups to Grams Converter use?**
grams = cups × grams per cup (ingredient density).

**Can I work backwards from the result?**
Yes. Type the result you want into Weight and the calculator finds the matching amount.
