How to Convert aJ to J?
Converting from aJ to J is a straightforward process. Follow these steps to ensure accurate conversions from attojoule to joule:
- Select the Attojoule Value: Start by determining the attojoule (aJ) value you want to convert into joule (J). This is your starting point.
- Multiply by the Conversion Factor: To calculate attojoule to equivalent joule amount, multiply the selected aJ value by 1e-18.
- Illustration of Multiplication:
- 1 aJ = 1e-18 J
- 10 aJ = 1e-17 J
- 100 aJ = 1e-16 J
- Find the Conversion Result: The result of this multiplication is your converted value in joule unit. This represents the same energy but in a different unit.
- Save Your Joule Value: After converting, remember to save the result. This value represents the energy you initially measured, now expressed in joules.
- Alternative Method – Division: If you prefer not to multiply, you can achieve the same conversion by dividing the attojoule value by 1e+18. This alternative method also gives you the correct energy in joules.
- Illustration of Division:
- J = aj ÷ 1e+18

Attojoule to Joule Examples
Example 1:
Convert 0.9 Attojoule energy to Joule unit.
Solution:
We know that one Attojoule is equivalent to 1e-18 Joule.
Therefore,
0.9 aJ = 0.9 x 1e-18 J.
0.9 aJ = 9e-19 J.
Hence, 0.9 Attojoule is approximately equal to 9e-19 Joule.
Example 2:
Convert 2 Attojoule energy to Joule unit.
Solution:
We know that one Attojoule is equivalent to 1e-18 Joule.
Therefore,
2 aJ = 2 x 1e-18 J.
2 aJ = 2e-18 J.
Hence, 2 Attojoule is approximately equal to 2e-18 Joule.
