Rolled Oats (Old Fashioned): How Many Grams in a Tablespoon?

By Fidamen-Chefsolver Team | Reviewed by Ugo Candido | Updated

Rolled oats are the poster child for density issues: they are flat, irregular, and create massive air gaps in a cup. A 'loose' cup weighs about 90g, but tap it on the counter and it can hit 120g! For consistent porridge or cookies that hold together, forget the cup and trust the scale.

FAQ

Rolled vs. Quick Oats: Can I swap them?
By weight? Yes. By volume? No. Quick oats are cut smaller and pack tighter, so 1 cup of quick oats weighs MORE than 1 cup of rolled oats. Always swap by grams (e.g., 100g for 100g).
