Oats Measurement FAQ
Everything you need to know about converting oats from weight to volume for cooking and baking.
One US cup of rolled oats weighs approximately 90 grams, while one Metric cup weighs about 85 grams. This can vary slightly depending on how tightly the oats are packed in the measuring cup.
Yes, significantly. Steel-cut oats are much denser and heavier, with 1 US cup weighing around 170 grams. Quick oats are lighter and more compact, weighing about 80 grams per US cup.
Use the ‘spoon and level’ method. Lightly spoon the oats into your measuring cup until it is heaping, then use the straight edge of a knife to level off the excess. Do not pack or press the oats down, as this will give you an inaccurate, heavier measurement.
No, oat flour has a different density than whole or rolled oats. One US cup of oat flour weighs approximately 100 to 110 grams. For the best results with baking, always use a digital kitchen scale for flour.
