Where these numbers come from

USDA FoodData Central, SR Legacy, food 16037: “Beans, navy, mature seeds, raw”. USDA lists these household measures for it:

1 cup = 208g

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.
