Where these numbers come from
USDA FoodData Central, SR Legacy, food 16398: “Peanut butter, smooth style, without salt”. USDA lists these household measures for it:
- 2 tbsp = 32g
- 1 cup = 258g
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.
