FAQ

How many grams is 1 cup of rolled oats?

89 grams (about 3.1 oz). Note: old-fashioned, not instant.

How many grams in a tablespoon of rolled oats?

5.6 g per US tablespoon (16 tablespoons to the cup), and 1.9 g per teaspoon.

Why do cup weights differ between websites?

Because volume measures depend on how the ingredient settles or packs. We use widely-published baking-standard weights (spooned-and-leveled for powders). A kitchen scale beats any chart.
