Cups to Grams Converter: Flour, Sugar, Butter and More
Pick an ingredient and see exactly what a cup, tablespoon or teaspoon weighs in grams — flour, sugar, butter, oil, milk and more. Plus the calories and macros of that amount, from our USDA food data.

Why a cup is not a fixed weight
A cup measures volume, not weight, and every ingredient has its own density. A cup of all-purpose flour is about 120 grams; a cup of almond flour only 96; a cup of granulated sugar 198. That is why bakers who care about consistency work in grams, and why a kitchen scale beats measuring cups.
Flour is the worst offender, because how you fill the cup changes the weight by a lot. Scooping packs it down; spooning it in and levelling keeps it light. The gram figure removes that guesswork.
How this converter works
Choose the ingredient, type the amount, and pick the unit you have — cups, tablespoons, teaspoons, ounces, sticks of butter or grams. You get the weight in grams, the volume equivalent, and the calories, protein, carbs, fat and fibre for that exact amount, drawn from our food data, sourced from USDA FoodData Central. That last part is what a plain converter cannot do.
Cup weights follow the King Arthur Baking ingredient weight chart — one source, on purpose, so the numbers stay consistent across ingredients.
Cups to grams, answered
How many grams is 1 cup of flour?
About 120 g for all-purpose or bread flour, 113 g for whole wheat, and just 96 g for almond flour. Because flour packs down when you scoop, weighing is far more accurate than measuring by volume.
Why do ingredients weigh different amounts per cup?
A cup is a fixed volume, but density varies. Sugar is heavy (198 g/cup), oil is lighter, and almond flour is very light — so one cup of each weighs something different.
How many tablespoons in a cup?
16 tablespoons make one cup, and 48 teaspoons. One tablespoon is one-sixteenth of a cup’s weight for that ingredient.
Is it better to bake by weight or by volume?
By weight. A kitchen scale removes the guesswork of how packed your cup is, which is the biggest source of inconsistent results — especially with flour.
