Where these numbers come from
USDA FoodData Central, SR Legacy, food 08120: “Cereals, oats, regular and quick, not fortified, dry”. USDA lists these household measures for it:
- 1 cup = 81g
- 0.333 cup = 27g
Fractions of a cup are the cup weight scaled down. The tablespoon figure is the cup weight divided by 16, since USDA doesn't list a tablespoon for this ingredient. The teaspoon is a third of the tablespoon. Metric-cup figures assume a 250ml cup, and Australian tablespoons hold 20ml. Weights under 10g are rounded to 0.1g, everything else to the nearest gram.
