Scale a label calorie value to your portion

Enter the amount you ate and the matching calorie value printed on a label or confirmed by the provider. This route does not save a diary; for a daily log, use the private calorie diary.

Your values

Use the same unit for eaten and reference amounts.

Result meaning and limits

The calculation is amount eaten ÷ reference amount × reference calories. Recipe, preparation and serving differences can change the real value. The result is not a daily target, diet plan, nutrient analysis, diagnosis or treatment recommendation.
