Where the numbers come from

Weights come from King Arthur Baking’s ingredient weight chart, read on 28 September 2026. For oats, the chart gives 1 cup = 89 g. Cups and spoons are US customary: 1 cup is 236.6 ml, 16 tablespoons or 48 teaspoons. A metric cup (250 ml) holds about 6% more.

Volume is only ever an estimate for dry ingredients: how tightly a cup is filled changes its weight. When a recipe gives grams, weigh.
