Why cups to grams depends on the ingredient
A cup measures volume, a gram measures weight, and different ingredients weigh different amounts per cup: a cup of flour is about 120 g, but a cup of sugar is about 198 g and a cup of honey 336 g. Weighing is more accurate, because how you fill the cup can change flour by 20% or more.
Example: 2 cups of all-purpose flour × 120 g = 240 g. Halving the recipe gives 120 g.

Dry ingredient weights follow King Arthur Baking's chart, which assumes flour is spooned into the cup and leveled. Liquids use their measured density. Butter: 1 stick = ½ cup = 113 g. For other units, see the unit converter, and oven temperatures in the temperature converter.
