## How to convert calories to megajoules (cal to MJ)

The formula for converting calories to megajoules is: MJ = cal × 0.0000041868. To calculate the calorie value in megajoules first substitute the calorie value into the preceding formula, and then perform the calculation. If we wanted to calculate 1 calorie in megajoules we follow these steps:

MJ = cal × 0.0000041868

MJ = 1 × 0.0000041868

MJ = 0.0000041868

In other words, 1 calorie is equal to 0.0000041868 megajoules.

## Example Conversion

Let's take a look at an example. The step-by-step process to convert 3 calories to megajoules is:

- Understand the conversion formula: MJ = cal × 0.0000041868
- Substitute the required value. In this case we substitute 3 for cal so the formula becomes: MJ = 3 × 0.0000041868
- Calculate the result using the provided values. In our example the result is: 3 × 0.0000041868 = 0.0000125604 MJ

In summary, 3 calories is equal to 0.0000125604 megajoules.

## Converting megajoules to calories

In order to convert the other way around i.e. megajoules to calories, you would use the following formula: cal = MJ × 238845.8966275. To convert megajoules to calories first substitute the megajoule value into the above formula, and then execute the calculation. If we wanted to calculate 1 megajoule in calories we follow these steps:

cal = MJ × 238845.8966275

cal = 1 × 238845.8966275

cal = 238845.8966275

Or in other words, 1 megajoule is equal to 238845.8966275 calories.
