What is the difference between

**calories**and**kilocalories**? The "**calorie**" we refer to in food is actually kilocalorie. One (1) kilocalorie is the same as one (1)**Calorie**(upper case C). A kilocalorie is the amount of heat required to raise the temperature of 1 kilogram of water one degree Celsius.Similarly, how do you calculate the percentage of calories from carbohydrates?

To

**calculate**the**percentage**of**carbohydrate**, take the grams of**carbohydrate**listed and multiply it by four. The result is the number of calories supplied by**carbohydrate**in that food. Divide this by the total calories and then multiply by 100 to convert the answer to a**percent**.How do you figure out KCAL?

A calorie is a unit that is used to measure energy. The Calorie you see on a food package is actually a

**kilocalorie**, or 1,000 calories. A Calorie (**kcal**) is the amount of energy needed to raise the temperature of 1 kilogram of water 1 degree Celsius.How do you calculate protein calories?

**Determine the percentage of protein in a given food.**

- Figure out how many grams of a protein a food contains. Divide that amount by the total calories in the food. Then multiply the sum by 100.
- For example, say a food contains 200 calories and 8 grams of protein. You would divide 200 by 8, giving you .25.
