How to convert megacalories to calories (Mcal to cal)

The formula for converting megacalories to calories is: cal = Mcal × 1000000. To calculate the megacalorie value in calories first substitute the megacalorie value into the preceding formula, and then perform the calculation. If we wanted to calculate 1 megacalorie in calories we follow these steps:

cal = Mcal × 1000000

cal = 1 × 1000000

cal = 1000000

In other words, 1 megacalorie is equal to 1000000 calories.

Example Conversion

Let's take a look at an example. The step-by-step process to convert 9 megacalories to calories is:

  1. Understand the conversion formula: cal = Mcal × 1000000
  2. Substitute the required value. In this case we substitute 9 for Mcal so the formula becomes: cal = 9 × 1000000
  3. Calculate the result using the provided values. In our example the result is: 9 × 1000000 = 9000000 cal

In summary, 9 megacalories is equal to 9000000 calories.

Converting calories to megacalories

In order to convert the other way around i.e. calories to megacalories, you would use the following formula: Mcal = cal × 0.000001. To convert calories to megacalories first substitute the calorie value into the above formula, and then execute the calculation. If we wanted to calculate 1 calorie in megacalories we follow these steps:

Mcal = cal × 0.000001

M1 = cal × 0.000001

Mcal = 0.000001

Or in other words, 1 calorie is equal to 0.000001 megacalories.

Conversion Unit Definitions

What is a Megacalorie?

A megacalorie (Mcal) is a unit of energy equivalent to one million calories (cal) or one thousand kilocalories (kcal). It represents a very large amount of energy and is often used in the context of large-scale energy measurements, particularly in the fields of nutrition and food industry, where significant quantities of energy need to be calculated.
To be precise: 1 Megacalorie (Mcal) = 1,000,000 calories (cal) = 1,000 kilocalories (kcal)
Megacalories are commonly used to express the energy content of large quantities of food, especially in agricultural and nutritional studies where the energy value of entire crops or food supplies is calculated.

What is a Calorie?

A calorie (cal) is a unit of energy commonly used in nutrition. It represents the amount of energy required to raise the temperature of one gram of water by one degree Celsius (or one degree Kelvin). In the context of nutrition, the term "calorie" usually refers to a kilocalorie, which is equal to 1,000 calories in scientific terms.
The energy content of food and beverages is often measured in kilocalories, abbreviated as kcal or Cal (with an uppercase "C" to distinguish it from the smaller "cal" used in physics).
In scientific terms, 1 kilocalorie is equal to 4.184 kilojoules (kJ). The conversion factor between kilocalories (kcal) and kilojoules (kJ) is 1 kcal = 4.184 kJ.
In everyday language, when people refer to the number of calories in food, they are usually referring to kilocalories. For example, if a food label says a serving contains 200 calories, it means 200 kilocalories or 200,000 calories in scientific terms.
