1 tablespoon of chopped apple weighs

Where these numbers come from

USDA FoodData Central, SR Legacy, food 09003: “Apples, raw, with skin”. USDA lists these household measures for it:

1 cup, quartered or chopped = 125g
1 cup slices = 109g
1 large (3-1/4" dia) = 223g
1 medium (3" dia) = 182g
1 small (2-3/4" dia) = 149g
1 extra small (2-1/2" dia) = 101g
1 NLEA serving = 242g

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.
