## How to convert watt hours to megajoules (Wh to MJ)

The formula for converting watt hours to megajoules is: MJ = Wh × 0.0036. To calculate the watt hour value in megajoules first substitute the watt hour value into the preceding formula, and then perform the calculation. If we wanted to calculate 1 watt hour in megajoules we follow these steps:

MJ = Wh × 0.0036

MJ = 1 × 0.0036

MJ = 0.0036

In other words, 1 watt hour is equal to 0.0036 megajoules.

## Example Conversion

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

- Understand the conversion formula: MJ = Wh × 0.0036
- Substitute the required value. In this case we substitute 3 for Wh so the formula becomes: MJ = 3 × 0.0036
- Calculate the result using the provided values. In our example the result is: 3 × 0.0036 = 0.0108 MJ

In summary, 3 watt hours is equal to 0.0108 megajoules.

## Converting megajoules to watt hours

In order to convert the other way around i.e. megajoules to watt hours, you would use the following formula: Wh = MJ × 277.77777777778. To convert megajoules to watt hours first substitute the megajoule value into the above formula, and then execute the calculation. If we wanted to calculate 1 megajoule in watt hours we follow these steps:

Wh = MJ × 277.77777777778

Wh = 1 × 277.77777777778

Wh = 277.77777777778

Or in other words, 1 megajoule is equal to 277.77777777778 watt hours.

## Conversion Unit Definitions
