Nutritionists usually talk about large amounts of calories, and hence, it is more useful to consider…
How are kilojoules and calories used to measure energy?
Food energy used to be measured in Calories (Cal) and some countries still use those units. The food and drinks we eat provide energy, which is measured in kilojoules. How much energy they provide depends on the amount of carbohydrate (sugars/starch), protein, fat and alcohol the food or drink contains, as well as the portion size.
How are calories measured on a food label?
