A cup of flour and a cup of sugar don’t weigh the same. Pick an ingredient, enter the amount and get the weight in grams, or the other way around. Weights come from the King Arthur Baking ingredient weight chart.
Key Takeaways
- Cups measure volume, grams measure weight, so every ingredient has its own conversion.
- King Arthur Baking counts 1 cup of all-purpose flour as 120 g and 1 cup of granulated sugar as 198 g.
- A kitchen scale gives the same result every time; how you fill a cup changes how much flour you get.
