How to Calculate Nutrients for Any Serving Size

Divide your actual serving by the label serving to get a ratio, then multiply each nutrient by that ratio.

Formula

Ratio = Your Serving / Label Serving

Your Nutrient = Label Nutrient x Ratio

Exemplo Resolvido

Cereal label says 30g serving has 140 calories and 3g protein. You eat 55g.

  1. Ratio = 55 / 30 = 1.83
  2. Your calories = 140 x 1.83 = 257 kcal
  3. Your protein = 3 x 1.83 = 5.5 g
