How to Convert Wh to MJ?
Converting from Wh to MJ is a straightforward process. Follow these steps to ensure accurate conversions from watt-hour to megajoule:
- Select the Watt-hour Value: Start by determining the watt-hour (Wh) value you want to convert into megajoule (MJ). This is your starting point.
- Multiply by the Conversion Factor: To convert watt-hour to megajoule, multiply the selected Wh value by 0.0036. This factor is essential for accurately converting from a smaller unit (Wh) to a much larger unit (MJ).
- Illustration of Multiplication:
- 1 Wh = 0.0036 MJ
- 10 Wh = 0.036 MJ
- 100 Wh = 0.36 MJ
- Find the Conversion Result: The result of this multiplication is your converted value in megajoule unit. This represents the same energy but in a different unit.
- Save Your Megajoule Value: After converting, remember to save the result. This value represents the energy you initially measured, now expressed in megajoules.
- Alternative Method – Division: If you prefer not to multiply, you can achieve the same conversion by dividing the watt-hour value by 277.777777778. This alternative method also gives you the correct energy in megajoules.
- Illustration of Division:
- MJ = wh ÷ 277.777777778

Watt-hour to Megajoule Examples
Example 1:
Convert 0.7 Watt-hour to Megajoule.
Solution:
We know that one Watt-hour is equivalent to 0.0036 Megajoule.
Therefore,
0.7 Wh = 0.7 x 0.0036 MJ.
0.7 Wh = 0.00252 MJ.
Hence, 0.7 Watt-hour is approximately equal to 0.00252 Megajoule.
Example 2:
Convert 10 Watt-hour to Megajoule.
Solution:
We know that one Watt-hour is equivalent to 0.0036 Megajoule.
Therefore,
10 Wh = 10 x 0.0036 MJ.
10 Wh = 0.036 MJ.
Hence, 10 Watt-hour is approximately equal to 0.036 Megajoule.
