3 cups of peanut butter in grams
3 cups × 270 g per cup = 810 g
A cup of peanut butter weighs 270 g, so 3 cups of it comes to 810 g. That figure is particular to peanut butter: a cup is a volume and a gram is a mass, and the only thing connecting them is how heavy the ingredient is for its bulk. Few things in a kitchen weigh more: a cup of it outweighs a cup of all-purpose flour by 2.3 times. The source line is "1/2 cup = 135 g", from King Arthur Baking.
