About these values

The record is whole milk with 3.25% milk fat and added vitamin D. The USDA record is "Milk, whole, 3.25% milkfat, with added vitamin D" (SR Legacy, FDC ID 171265). It gives 3.15 g of protein and 61 kcal per 100 g.

Protein in a portion is its weight times the protein per 100 g, divided by 100. For 1 cup of milk: 244 × 3.15 ÷ 100 = 7.7 g. Values on this page are rounded to 0.1 g.

A packaged food's own label can differ from the USDA average. When you have the label, its numbers are the ones for that product.
