Where this number comes from
USDA FoodData Central lists 1 serving 8 fl oz of “Beverages, water, tap, drinking” at 237 g (FDC ID 173647, SR Legacy).USDA lists water by the 8 fl oz serving, which is exactly one US cup.
Everything else is worked out from that figure: spoons from 1 cup = 16 tablespoons = 48 teaspoons, and ounces and pounds from their exact definitions (1 oz = 28.349523125 g, 1 lb = 453.59237 g, NIST).
