Kcal vs. Cal: Know the Difference
By Shumaila Saeed || Published on January 18, 2024
"Kcal (kilocalorie) is 1,000 calories, while Cal (calorie) is a smaller unit; both measure energy in food."
Key Differences
Kcal, short for kilocalorie, is a unit of energy equal to 1,000 calories. Cal, on the other hand, represents a single calorie, a much smaller unit of energy. Kcals are commonly used in dietary contexts to signify the energy content in food.

In scientific terms, a Cal (calorie) is the amount of energy needed to raise the temperature of 1 gram of water by 1 degree Celsius. A Kcal (kilocalorie) is 1,000 times larger, representing the energy to raise the temperature of a kilogram of water by the same amount.

On nutrition labels, calories are often listed as Kcals, although the term 'calories' is more popularly used. This can cause confusion, as a dietary calorie (Cal) is technically a kilocalorie (Kcal) in scientific terms.
