Why is food measured in calories?

A calorie is a unit of measure of energy. Very specifically, it is the amount of energy that is required to raise the temperature of one mL, (which is also one gram), of water by one degree Celsius.

Does anyone use kJ instead of calories?

You might be surprised to know that nearly every country on the planet officially uses kilojoules. Whilst Australia switched over to the metric system, and thus from using calories to kilojoules in the 70’s confusion still abounds.

Why is it important to understand calories?

Calories and health. The human body needs calories to survive. Without energy, the cells in the body would die, the heart and lungs would stop, and the organs would not be able to carry out the basic processes needed for living. People absorb this energy from food and drink.
