Cups to Grams Converter
Loading ingredient-aware converter…
Converting cups to grams isn’t always a single fixed number—different ingredients have different densities. This cups to grams converter lets you choose an ingredient (such as all-purpose flour, granulated sugar, brown sugar, butter, or other common baking items) and then converts cups into grams based on that selection.
It’s especially useful when you’re following recipes from different countries, scaling a recipe up or down, or switching between US cup measurements and metric weights. Enter the number of cups, pick the ingredient, and you’ll get the grams result instantly.
Because ingredient weights can vary by brand, how tightly something is packed, and how you measure (scooped vs spooned flour), treat results as a reliable starting point rather than a lab-grade value. When precision matters, use a kitchen scale and follow the recipe’s specific ingredient guidance.

How it works
(Ingredient-aware: grams = cups × grams-per-cup for the selected ingredient.)
Examples
- 1 cup (all-purpose flour) ≈ 120–125 g (reference-dependent)
- 1 cup (granulated sugar) ≈ 200 g (reference-dependent)

FAQ
Why do cups to grams depend on the ingredient?
Because ingredients have different densities, so the same volume can weigh different amounts.
How many grams are in 1 cup of flour?
It depends on the flour type and method, but many references use about 120–125 g for all-purpose flour.
How many grams are in 1 cup of sugar?
Granulated sugar is often about 200 g per cup (varies by source and packing).
Are these conversions exact?
No—treat them as best estimates; measurement and packing can change the weight.
Should I use a scale for baking?
Yes—weights are usually more consistent than volume for baking.
