Wh to aj Conversion Formula:
One Watt-hour is equal to 3.6e+21 Attojoule.
Formula: 1 Wh = 3.6e+21 aJ
By using this conversion factor, you can easily convert any energy from watt-hour to attojoule with precision.
How to Convert Wh to aJ?
Converting from Wh to aJ 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 (aJ). 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 (aJ).
- Illustration of Multiplication:
- 1 Wh = 3.6e+21 aJ
- 10 Wh = 3.6e+22 aJ
- 100 Wh = 3.6e+23 aJ
- 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:
- aJ = wh ÷ 2.777778e-22

Watt-hour to Attojoule Examples
Example 1:
Convert 0.5 Watt-hour to Attojoule.
Solution:
We know that one Watt-hour is equivalent to 3.6e+21 Attojoule.
Therefore,
0.5 Wh = 0.5 x 3.6e+21 aJ.
0.5 Wh = 1.8e+21 aJ.
Hence, 0.5 Watt-hour is approximately equal to 1.8e+21 Attojoule.
Example 2:
Convert 9 Watt-hour to Attojoule.
Solution:
We know that one Watt-hour is equivalent to 3.6e+21 Attojoule.
Therefore,
9 Wh = 9 x 3.6e+21 aJ.
9 Wh = 3.24e+22 aJ.
Hence, 9 Watt-hour is approximately equal to 3.24e+22 Attojoule.
Example 3:
Convert 86 Watt-hour to Attojoule.
Solution:
We know that one Watt-hour is equivalent to 3.6e+21 Attojoule.
