How it is calculated
Teaspoons = sugar grams ÷ grams per teaspoon (4 g by default). Calories = grams × 4. WHO limit = 10% of calories ÷ 4, and the share = grams ÷ limit × 100.
Example
Inputs: Sugar = 39 g, Grams per teaspoon = 4 g, Your daily calories = 2,000 kcal/day. Result: Teaspoons: 9.8; Sugar calories: 156 kcal; Share of WHO limit (10%): 78%.
Limits and caveats
- A teaspoon of white sugar weighs about 4 to 4.2 g depending on how it is filled, so you can change it.
- Label sugar can include natural milk and fruit sugars, while the WHO limit covers free sugars.
