What Is a Kilocalorie (kcal)?

A kilocalorie (kcal) is a unit used to measure energy.

Just as a kilometer is 1,000 meters, one kilocalorie is equal to 1,000 small calories (cal).

It's the most common unit for discussing the energy content of food.

Kilocalorie vs. Calorie: What's the Difference?

Have you ever noticed the word "Calories" on a food label? What you're actually seeing is a kilocalorie (kcal).

Here's the simple breakdown:

1 Calorie (with a capital C), also known as a food Calorie, is equal to 1 kilocalorie (kcal).
1 kilocalorie (kcal) is equal to 1,000 calories (with a lowercase c).

Essentially, in the world of nutrition, the terms Calorie and kilocalorie are used interchangeably.

The "small calorie" (cal) is a much smaller unit and is primarily used in science labs.

How Are Kilocalories Measured?

Scientifically, a kilocalorie is the amount of energy needed to heat one kilogram of water by one degree Celsius.

This precise measurement allows scientists to determine how much energy your body can get from the macronutrients in your food, such as:

Carbohydrates
Proteins
Fats

When a food label says a serving has 100 Calories, it means that's the amount of energy your body can use from it.

More Than Just Food: Other Uses for the Kilocalorie

The kilocalorie isn't just for food!

As a fundamental unit of energy, it's also used in fields like physics and chemistry to measure energy in chemical reactions and heat transfer.
