What is Joule to Attojoule Conversion?
Joule (J) and attojoule (aJ) are both units used to measure energy, but they serve different purposes depending on the scale of the measurement. If you ever need to convert joule to attojoule, knowing the exact conversion formula is essential.
J to aj Conversion Formula:
One Joule is equal to 1e+18 Attojoule.
Formula: 1 J = 1e+18 aJ
By using this conversion factor, you can easily convert any energy from joule to attojoule with precision.
How to Convert J to aJ?
Converting from J to aJ is a straightforward process. Follow these steps to ensure accurate conversions from joule to attojoule:
- Select the Joule Value: Start by determining the joule (J) value you want to convert into attojoule (aJ). This is your starting point.
- Multiply by the Conversion Factor: To convert joule to attojoule, multiply the selected J value by 1e+18. This factor is essential for accurately converting from a larger unit (J) to a much smaller unit (aJ).
- Illustration of Multiplication:
- 1 J = 1e+18 aJ
- 10 J = 1e+19 aJ
- 100 J = 1e+20 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 joule value by 1e-18. This alternative method also gives you the correct energy in attojoules.
- Illustration of Division:
- aJ = j ÷ 1e-18

Joule to Attojoule Examples
Example 1:
Convert 0.1 Joule to Attojoule.
Solution:
We know that one Joule is equivalent to 1e+18 Attojoule.
Therefore,
0.1 J = 0.1 x 1e+18 aJ.
0.1 J = 1e+17 aJ.
Hence, 0.1 Joule is approximately equal to 1e+17 Attojoule.
Example 2:
Convert 6 Joule to Attojoule.
Solution:
We know that one Joule is equivalent to 1e+18 Attojoule.
Therefore,
6 J = 6 x 1e+18 aJ.
6 J = 6e+18 aJ.
Hence, 6 Joule is approximately equal to 6e+18 Attojoule.
Example 3:
Convert 22 Joule to Attojoule.
Solution:
We know that one Joule is equivalent to 1e+18 Attojoule.
Therefore,
22 J = 22 x 1e+18 aJ.
22 J = 2.2e+19 aJ.
Hence, 22 Joule is approximately equal to 2.2e+19 Attojoule.
Example 4:
