Answer :
The two ways to measure energy in food are Joules and Calories.
Energy is defined as the ability or capacity to work. The types of mechanical energy that we have are both potential and kinetic energy.
Both types of energy are useful in our everyday lives. The units of the energy are the same. They are both measured in Joules.
Due to this reason, we can also categorize the ways to measure energy in food as both in Joules (J) or calories. For nutrition, the label usually has calories as their measure of energy while the metric system uses Joules.
