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

The formula for converting megajoules to watt hours is: Wh = MJ × 277.77777777778. To calculate the megajoule value in watt hours first substitute the megajoule value into the preceding formula, and then perform 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

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

## Example Conversion

Let's take a look at an example. The step-by-step process to convert 8 megajoules to watt hours is:

- Understand the conversion formula: Wh = MJ × 277.77777777778
- Substitute the required value. In this case we substitute 8 for MJ so the formula becomes: Wh = 8 × 277.77777777778
- Calculate the result using the provided values. In our example the result is: 8 × 277.77777777778 = 2222.22222222224 Wh

In summary, 8 megajoules is equal to 2222.22222222224 watt hours.

## Converting watt hours to megajoules

In order to convert the other way around i.e. watt hours to megajoules, you would use the following formula: MJ = Wh × 0.0036. To convert watt hours to megajoules first substitute the watt hour value into the above formula, and then execute 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

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