Cal vs. Kcal: What's the Difference?
Edited by Sawaira Riaz || By Sumera Saeed || Updated on October 10, 2023
A cal (calorie) is a unit of energy, and a kcal (kilocalorie) is equal to 1000 calories. Often, kcal is used in nutritional contexts, while cal is used in scientific contexts.
Key Differences
Cal and kcal both represent units of energy, albeit in different magnitudes. The cal is the basic unit of energy in the International System of Units, while kcal, on the other hand, is a larger unit.
