In nutrition, kcal (kilocalories) and calories refer to the same unit of energy. You can read kcal simply as calories — no conversion is needed.
We use kcal in the app to match standard nutrition labels on food packaging and ensure consistency worldwide.
At the moment, the app does not support kilojoules (kJ) and displays energy values only in kcal for simplicity. If you’d like to convert kcal to kJ manually, use the following formula: 1 kcal = 4.184 kJ
Example:
200 kcal × 4.184 = 837 kJ
This way, you can easily interpret and compare energy values, even if your food packaging uses different units.
