Cups to Grams Converter

What Is the Cups to Grams Converter?

The Cups to Grams Converter accounts for the fact that a cup measures volume while grams measure mass. It uses ingredient-specific bulk density, supports US and metric cup standards, converts in either direction and includes a recipe ledger for scaling several ingredients together. A custom-density option handles products outside the built-in reference list.

How It Works

Choose an ingredient and cup standard, enter an amount and select volume or mass units. The scale readout shows the converted amount, density and assumptions. In Recipe Batch mode, add ingredient lines and change the scale factor to produce a consolidated gram schedule that can be copied or exported. Values are estimates because packing, humidity and product grind affect density.

When to Use It

Use it when adapting a volume-based recipe to a kitchen scale, converting an international recipe, scaling a batch or creating a consistent prep sheet. Use the package label or a tested kitchen weight for precision-sensitive baking.

Frequently Asked Questions

Why Do Different Ingredients Have Different Grams Per Cup?

Equal volumes of flour, sugar, butter and water contain different amounts of mass. The conversion must use the selected ingredient's bulk density.

What Is The Difference Between US And Metric Cups?

A US customary cup is exactly 236.5882 milliliters for conversion purposes, while a metric cup is 250 milliliters. Some home-cooking references round the US cup to 240 milliliters, so follow the standard used by the recipe publisher.

Are The Ingredient Weights Exact?

No. Scooping method, compaction, humidity, grind and brand can change a cup's weight. The displayed density is an explicit reference assumption and can be replaced with a custom tested density.
