How to measure rolled oats accurately

For the most reliable baking results, weigh rolled oats on a kitchen scale rather than scooping by volume. One US cup of rolled oats weighs about 90 grams, but the exact figure changes with how tightly it's packed and the brand. Use the table above for quick reference, or the converter for any custom amount.
