PackHow many calories are in the whole package?
Labels print energy per 100 g, not for the pack you are holding. Type the two numbers from the label and PackCal answers instantly, with portions, a "how much can I eat?" calculator, and side-by-side comparison.

One formula, every package size
Works for a 30 g bar and a 1 kg bag alike. PackCal never assumes a package is at least 100 g.
total = kcal per 100 × package size ÷ 100
Built to be used in the supermarket aisle
Open, type two numbers, done. Everything else is there when you want it and out of the way when you don't.
