About this calculator
A cup of flour is not a fixed amount: scoop and pack it and you fit half as much again as a gently spooned cup. That variability is why cup-based recipes bake inconsistently and why serious bakers weigh ingredients. This converter turns cups into grams by ingredient, so you can swap a wobbly volume for a precise weight.
Formula explained
Grams = Cups × grams-per-cup, and grams-per-cup is set by the ingredient’s density. There is no single number: flour ≈ 120 g, granulated sugar ≈ 200 g, butter ≈ 227 g, honey ≈ 336 g per US cup. One US cup is 236.6 ml.
Worked example
1 cup of all-purpose flour = 120 g, about 236 ml. Weigh 120 g and you have exactly what the recipe intends.
Tips & notes
- Keep a digital scale with 0.1 g resolution; it is cheap and accurate.
- Tare the bowl before each ingredient so you weigh only what you add.
- When a recipe gives both cups and grams, trust the grams.
