Each row is USDA’s 1-cup weight (258 g) times the amount. A tablespoon is 1/16 cup and a teaspoon is 1/48 cup, so 1 tbsp = 258 ÷ 16 = 16.1 g. Ounces are grams ÷ 28.3495. USDA also weighed small measures on their own (2 tbsp: 32 g). Those can differ from the cup-based rows by a few tenths of a gram because each weight is rounded.
