Where these numbers come from
USDA FoodData Central, SR Legacy, food 11282: “Onions, raw”. USDA lists these household measures for it:
- 1 cup, chopped = 160g
- 1 cup, sliced = 115g
- 1 tbsp chopped = 10g
- 1 large = 150g
- 1 slice, large (1/4" thick) = 38g
- 1 medium (2-1/2" dia) = 110g
- 1 slice, medium (1/8" thick) = 14g
- 1 small = 70g
- 1 slice, thin = 9g
- 10 rings = 60g
Fractions of a cup are the cup weight scaled down. 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. Full source list.
