Answer:
calorie
Step-by-step explanation:
Calories are a unit of measure based on the specific heat of water and express the energy power of food.

- A calorie is the amount of energy needed to raise the temperature of 1 gram of water to 1 ° C.
- A kilocalorie is the amount of energy needed to raise the temperature of 1 kilogram of water to 1ºC, therefore, one kilocalorie equals one thousand calories.
- One kilocalorie equals 4,185 kiloJoules.
