Where these numbers come from
USDA FoodData Central, SR Legacy, food 19334: “Sugars, brown”. USDA lists these household measures for it:
- 1 tsp unpacked = 3g
- 1 cup packed = 220g
- 1 cup unpacked = 145g
- 1 tsp packed = 4.6g
- 1 tsp brownulated = 3.2g
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. 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.
