Cups to grams by ingredient
Convert a US cup measurement to grams for common baking ingredients — useful when a recipe uses cups but your scales measure in grams.

Amount in grams
How to use this calculator
- Choose the ingredient.
- Enter the amount in cups.
- Read the equivalent weight in grams.
Assumptions
- Uses standard approximate weight-per-cup figures for each ingredient — how an ingredient is packed (sifted vs scooped, packed vs loose) can shift the real weight by 10–15%.
Technical details: what the fields mean
- Ingredient
ingredient - Different ingredients pack very differently into a cup — flour is much lighter per cup than sugar or butter.
- Amount
cups - Amount in US cups, as given in the recipe.
Methodology
Grams = cups × grams-per-cup for the chosen ingredient — these figures are standard approximate baking references, since a 'cup' is a volume measure and different ingredients pack to different densities.
Worked example
2 cups of flour
Inputs: ingredient=Flour, cups=2
Result: 240.0g
Practical guidance
- Weighing ingredients on a scale is more accurate and repeatable than cup measures, especially for flour, which packs very inconsistently by volume.
Common mistakes
- Using the same grams-per-cup figure for every ingredient — flour, sugar and butter all pack very differently.
FAQs
How many grams is a cup of flour?
About 120g for plain/all-purpose flour, using a standard US cup — this varies somewhat by how the flour is packed.
