How It Works

Cups measure volume, while grams measure mass. Because different ingredients have different densities, there is no single cups-to-grams conversion factor. This converter uses ingredient-specific reference weights to calculate the equivalent mass.

Example

For example, 1 cup of all-purpose flour is approximately 120 grams, while 1 cup of granulated sugar is approximately 200 grams. The exact weight depends on the ingredient and its preparation.

Frequently Asked Questions

How many grams are in a cup?

The number of grams in a cup depends on the ingredient. For example, 1 cup of all-purpose flour is approximately 120 grams, while 1 cup of granulated sugar is approximately 200 grams.

How do you convert cups to grams?

Select the ingredient and multiply the number of cups by that ingredient's grams-per-cup reference value. Different ingredients have different densities, so the conversion depends on the ingredient.

How many grams are in 1 cup of flour?

One cup of all-purpose flour is approximately 120 grams. The exact weight can vary depending on how the flour is measured, packed, or sifted.

How many grams are in 1 cup of sugar?

One cup of granulated sugar is approximately 200 grams.

How many grams are in 1 cup of butter?

One cup of butter is approximately 227 grams.

Why do different ingredients have different cup-to-gram conversions?

A cup measures volume, while a gram measures mass. Ingredients have different densities, so the same volume can have a different weight depending on the ingredient.

Is a cups-to-grams conversion exact?

No. Ingredient weight can vary with density, moisture, packing, and preparation. These values are standard cooking and baking references, while weighing an ingredient with a kitchen scale provides greater precision.

Is cups to grams the same as cups to milliliters?

No. Cups to milliliters converts volume to volume, while cups to grams converts volume to mass. A cups-to-grams conversion therefore depends on the ingredient.
