how labels translate cal in english meaning
Nutrition facts use Calories to summarize how much usable energy a product provides in an average serving. Serving sizes on the label are chosen to match how people actually eat, so you can multiply or divide to match your portion.
Manufacturers calculate this by adding energy from protein, carbohydrates, fat, and sometimes alcohol, then converting each to Calories using standard Atwater factors that reflect how well your body can use them.
