How to measure ingredients

How to convert dry rolled oats

Our reference is 89 grams per US reference cup of dry rolled oats, dry old-fashioned or quick oats; not cooked oats or oat flour. That works out to about 0.3762 grams per millilitre, so cups = grams ÷ 89 and grams = cups × 89 in US customary measures.

For metric and Australian recipes the cup holds 250 ml, so one cup of dry rolled oats is about 94.05 grams. Australian tablespoons hold 20 ml rather than 15 ml, which the calculator handles when you pick that system.

Preparation changes the weight

The reference describes dry rolled oats as: dry old-fashioned or quick oats; not cooked oats or oat flour. A different form, such as sifted, packed, melted, chopped or cooked, can hold a different weight in the same cup and needs its own reference. When a recipe gives a gram amount, weigh that amount instead of converting.

Brand, moisture and how firmly the cup is filled all move the practical result. Treat the numbers here as recipe equivalents, not laboratory densities.

Where the number comes from

The reference comes from King Arthur Baking ingredient weight chart, which lists 1 cup as 89 grams. Published recipe weight, normalised to one reference cup. This site assigns the published cup weight to its adopted US reference cup of 236.5882365 ml; the source itself does not define an exact millilitre cup volume. Checked September 25, 2026.
