About these values
The record is roasted breast meat without skin or bone, so the weights are cooked weights. Raw breast weighs more for the same protein, because cooking removes water. The USDA record is "Chicken, broilers or fryers, breast, meat only, cooked, roasted" (SR Legacy, FDC ID 171477). It gives 31.02 g of protein and 165 kcal per 100 g.
Protein in a portion is its weight times the protein per 100 g, divided by 100. For half a chicken breast: 86 × 31.02 ÷ 100 = 26.7 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.
