How to Convert Wh to Attojoule?
Converting from Wh to Attojoule is a straightforward process. Follow these steps to ensure accurate conversions from watt-hour to attojoule:
- Select the Watt-hour Value: Start by determining the watt-hour (Wh) value you want to convert into attojoule (Attojoule). This is your starting point.
- Multiply by the Conversion Factor: To convert watt-hour to attojoule, multiply the selected Wh value by 3.6e+21. This factor is essential for accurately converting from a larger unit (Wh) to a much smaller unit (Attojoule).
- Illustration of Multiplication:
- 1 Wh = 3.6e+21 Attojoule
- 10 Wh = 3.6e+22 Attojoule
- 100 Wh = 3.6e+23 Attojoule
- Find the Conversion Result: The result of this multiplication is your converted value in attojoule unit. This represents the same energy but in a different unit.
- Save Your Attojoule Value: After converting, remember to save the result. This value represents the energy you initially measured, now expressed in attojoules.
- Alternative Method – Division: If you prefer not to multiply, you can achieve the same conversion by dividing the watt-hour value by 2.777778e-22. This alternative method also gives you the correct energy in attojoules.
- Illustration of Division:
- Attojoule = wh ÷ 2.777778e-22

Watt-hour to Attojoule Examples
Example 1:
Convert 0.7 Watt-hour to Attojoule.
Solution:
We know that one Watt-hour is equivalent to 3.6e+21 Attojoule.
Therefore,
0.7 Wh = 0.7 x 3.6e+21 Attojoule.
0.7 Wh = 2.52e+21 Attojoule.
Hence, 0.7 Watt-hour is approximately equal to 2.52e+21 Attojoule.
Example 2:
Convert 5 Watt-hour to Attojoule.
Solution:
We know that one Watt-hour is equivalent to 3.6e+21 Attojoule.
