Panel energy
The visitor types energy, protein, fat and carbohydrate per 100 g, then the grams on the scale. The tool scales every figure to that portion. The panel they hold is the input. The same search exists in German, French, Spanish and Portuguese, so the host ships all nine languages.
Pick a unit or a code and convert it. The output is the converted figure, ready to copy.
This is a general-purpose tool, not medical, legal or financial advice. Figures are estimates from published food data or arithmetic. A qualified professional owns decisions that affect your health.
How to use it
Inputs are per-100 g figures and a weight. Computation scales. Output is the portion.
