1 Cup Oats in Grams
1 cup of oats weighs:
90g
US cup (240 ml)
94g
Metric / AU cup (250 ml)
American recipes mean the 240 ml cup; Australian, British and New Zealand recipes mean the 250 ml metric cup. If the recipe does not say, the cuisine usually tells you — see the full cups to grams guide.
Rolled oats are light and flaky, at about 90 g per cup — one of the lightest common baking ingredients by volume. Steel-cut oats are much denser because the grain is chopped rather than flattened.
