Rolled Oats (Old Fashioned)
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.

How this conversion works
Milliliters measure volume while grams measure weight. Because Rolled Oats (Old Fashioned) has a density of 0.38 g/mL, 10 mL weighs 4 g — not 10 g as it would for water. This converter uses the real density of Rolled Oats (Old Fashioned) so every measurement is accurate.
Measurement notes
Values are rounded to the nearest whole gram. Actual weight can vary slightly with compaction, temperature, and brand. For precision baking, a kitchen scale is always more reliable than volume measurements.

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).
