Metric cups and other cup sizes
The figures above use the US customary cup of 236.6 ml. A metric cup is 250 ml, so a metric cup of rolled oats weighs about 93 grams. UK recipes that say "cup" usually mean a 250 ml metric cup, which is why weighing in grams is more reliable than measuring by volume.
Measuring rolled oats accurately
Spoon rolled oats lightly into a dry measuring cup and level the top without shaking or packing them down. Oats settle easily, so scooping directly from the bin compresses them and yields too much. Weighing oats in grams guarantees the correct ratio of dry ingredients to liquids.
