How to convert megajoules to kilocalories (MJ to kcal)

The formula for converting megajoules to kilocalories is: kcal = MJ × 238.8458966275. To calculate the megajoule value in kilocalories first substitute the megajoule value into the preceding formula, and then perform the calculation. If we wanted to calculate 1 megajoule in kilocalories we follow these steps:

kcal = MJ × 238.8458966275

kcal = 1 × 238.8458966275

kcal = 238.8458966275

In other words, 1 megajoule is equal to 238.8458966275 kilocalories.

Example Conversion

Let's take a look at an example. The step-by-step process to convert 7 megajoules to kilocalories is:

  1. Understand the conversion formula: kcal = MJ × 238.8458966275
  2. Substitute the required value. In this case we substitute 7 for MJ so the formula becomes: kcal = 7 × 238.8458966275
  3. Calculate the result using the provided values. In our example the result is: 7 × 238.8458966275 = 1671.9212763925 kcal

In summary, 7 megajoules is equal to 1671.9212763925 kilocalories.

Converting kilocalories to megajoules

In order to convert the other way around i.e. kilocalories to megajoules, you would use the following formula: MJ = kcal × 0.0041868. To convert kilocalories to megajoules first substitute the kilocalorie value into the above formula, and then execute the calculation. If we wanted to calculate 1 kilocalorie in megajoules we follow these steps:

MJ = kcal × 0.0041868

MJ = 1 × 0.0041868

MJ = 0.0041868

Or in other words, 1 kilocalorie is equal to 0.0041868 megajoules.

Conversion Unit Definitions

What is a Megajoule?

A megajoule (MJ) is a metric unit of energy in the International System of Units (SI). One megajoule is equal to 1,000,000 joules or 1×106 joules. The prefix "mega-" signifies a factor of one million, so a megajoule is a large unit of energy, often used in contexts where significant amounts of energy are involved.
Megajoules are commonly used in various scientific, engineering, and industrial applications to measure large quantities of energy. For instance, in the field of nutrition, the energy content of food is sometimes measured in megajoules per serving. In energy-related contexts, such as electricity generation or large-scale industrial processes, the energy output or consumption is often expressed in megajoules.

What is a Kilocalorie?

A kilocalorie (kcal), commonly referred to as a Calorie with an uppercase "C," is a unit of energy used in the field of nutrition and dietary measurement. It represents the amount of energy required to raise the temperature of one kilogram of water by one degree Celsius. In scientific terms, 1 kilocalorie is equal to 1,000 calories (lowercase "c"), which are the smaller units used in physics.
In the context of nutrition, the energy content of food and beverages is often measured in kilocalories. For example, if a food item contains 100 kilocalories, it means consuming that food provides the body with 100,000 calories of energy. Kilocalories are widely used on food labels and dietary recommendations to indicate the energy content of various foods and drinks.
