Rolled Oats has a density of approximately 90g per cup. Old-fashioned rolled oats. Quick oats run closer to 95g. Source: USDA FoodData Central. This is the figure used everywhere on this page, including the tablespoon and teaspoon values, so the numbers stay consistent whether you're reading the summary line, the table, or the FAQ answers below.

How 800g Converts, Step by Step

cups = grams ÷ grams per cup

800g divided by 90g (the weight of one cup of rolled oats) equals 8.89 cups. Multiplying that by 16 gives 142.2 tablespoons, and by 48 gives 426.7 teaspoons, since one cup always equals 16 tablespoons or 48 teaspoons regardless of the ingredient.

Rolled Oats is lighter than water, which weighs about 236g per cup. That's why 800g of rolled oats takes up more volume (2103ml) than the same weight of water would (802ml). For a side-by-side look at how other ingredients compare, see the 800 grams to cups page.

If You're Using a Metric or Imperial Cup

The 8.89 cup figure above uses the US Customary cup (236.588ml). Recipes written outside the US sometimes use a metric cup (250ml) or an imperial (uk) cup (284.131ml) instead. At 800g, that's 8⅜ metric cups or 7⅜ imperial cups of rolled oats, close to the US figure but not identical. The cup standard switch in the converter above recalculates this instantly for any gram amount.

Scaling This 800g Amount

Doubling a recipe that calls for 800g of rolled oats means weighing 1,600g, or measuring 17.78 cups if you're working by volume instead of weight. Halving it means 400g, or 4.44 cups. Weight scales exactly with simple multiplication; cup measurements compound any scooping error each time they're doubled or halved, so weighing is more reliable the more a recipe is scaled.

Rolled Oats Next to Other Dry Goods

Within dry goods, density still varies by ingredient. At 800g, cocoa powder (85g per cup) measures 9⅜ cups, while protein powder (120g per cup) measures 6⅔ cups, compared to 8⅞ cups for rolled oats. Swapping ingredients in a recipe by cup measurement alone, without adjusting for this difference, changes the actual weight used.
