Mathematical Formula & Step-by-Step Example

Weight in Grams = Volume in Cups × (Ingredient Density in Grams per US Cup)

Worked Step-by-Step Example

To convert 1.5 cups of packed brown sugar (density 220g/cup): 1.5 cups × 220g/cup = 330 grams.

Understanding Cups to Grams Converter in Professional Baking

Translating cups to grams is the single most effective way to eliminate baking failures. Volume measurements are notoriously variable because humidity, storage settling, and scooping technique alter how densely ingredients pack into a cup. Weighing out ingredients on a digital kitchen scale guarantees reproducible crusts, tender cake crumbs, and balanced doughs.

Our converter maps volumetric cup fractions directly to mass using verified density metrics. Whether you are working with delicate cake flour, heavy whole wheat, viscous honey, or solid shortening, entering the cup volume yields instant scale-ready gram measurements.

When converting full recipes, keep in mind that liquids and dry ingredients behave differently. Liquids maintain fixed density (water is always 236.59g per US cup), whereas dry powders change density based on sifting or packing. Using our ingredient-specific selector guarantees exact mass matching.

Frequently Asked Questions

How many grams is 1 cup of all-purpose flour?

One US customary cup of spooned and leveled all-purpose flour weighs 125 grams (4.41 oz).

How many grams is 1 cup of granulated sugar?

One US customary cup of granulated white sugar weighs 200 grams (7.05 oz).

How many grams is 1 cup of butter?

One US customary cup of butter (2 sticks / 8 ounces) weighs 227 grams.

Why does 1 cup of flour weigh different amounts in different recipes?

Different sources use different cup weight baselines. King Arthur specifies 120g per cup, USDA uses 125g, and Gold Medal recommends 128g. Our database defaults to the 125g standard.

Should I weigh brown sugar packed or loose?

Standard baking recipes expect brown sugar to be firmly packed into the cup measure, which yields approximately 220 grams per cup.

How do I convert cups to grams for baking recipes?

Multiply the number of cups by the ingredient density figure in grams per cup (Weight in Grams = Volume in Cups × Density in Grams per Cup).

What is the fastest way to convert American recipes for European scales?

Use this cups to grams converter to look up each ingredient in your recipe and zero out your digital kitchen scale as you add each weight in sequence.
