Wh to MJ | Convert Watt-hour to Megajoule

Watt-hour to Megajoule Conversion Formula

To convert from Watt-hour (Wh) to Megajoule (MJ), use the following formula:

$\textbf{ Megajoule} \text{ (MJ)}$

$= 60 \times 60 \times \frac{1}{10^{6}}\times \textbf{ Watt-hour} \text{ (Wh)}$

$= 0.0036\times \textbf{ Watt-hour} \text{ (Wh)}$

Example

Let's convert 5 Watt-hour (Wh) to Megajoule (MJ).

Using the formula:

$5 \times 0.0036 = 0.018$

Therefore, 5 Watt-hour (Wh) is equal to $0.018$ Megajoule (MJ).
