What is a Kilocalorie?

A kilocalorie (kcal) is a unit of energy equal to the amount of heat required to raise the temperature of one kilogram of water by one degree Celsius. It's commonly used in nutrition and food science, where it's often simply called a "calorie" (with a capital C).

What is a Megajoule?

A megajoule (MJ) is a unit of energy in the International System of Units (SI). One megajoule equals one million joules, making it a convenient unit for measuring larger amounts of energy in scientific and industrial applications.

Conversion Formula

To convert kilocalories to megajoules, multiply the number of kilocalories by 0.004184. This conversion factor is based on the exact relationship between these units in the SI system.
