Where these numbers come from

USDA FoodData Central, SR Legacy, food 19350: “Syrups, corn, light”. USDA lists these household measures for it:

1 cup = 341g
1 tbsp = 22g

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.
