Why does the ingredient matter?
Volume measures the room an ingredient takes up. Grams measure its mass. A level cup of rolled oats and the same cup filled with packed brown sugar give very different scale readings.
Here, one US cup contains 16 US tablespoons or 48 US teaspoons. An Australian tablespoon or a 250 mL metric cup needs a different conversion. For a recipe that includes a gram weight, use the author’s weight.
Reference weights come from the King Arthur Baking ingredient chart. Read more about US kitchen units at NIST.
