What is Attojoule to Kilojoule Conversion?
Attojoule (aJ) and kilojoule (kJ) 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 attojoule to kilojoule, knowing the exact conversion formula is essential.
AJ to kj Conversion Formula:
One Attojoule is equal to 1e-21 Kilojoule.
Formula: 1 aJ = 1e-21 kJ
By using this conversion factor, you can easily convert any energy from attojoule to kilojoule with precision.
How to Convert aJ to kJ?
Converting from aJ to kJ is a straightforward process. Follow these steps to ensure accurate conversions from attojoule to kilojoule:
- Select the Attojoule Value: Start by determining the attojoule (aJ) value you want to convert into kilojoule (kJ). This is your starting point.
- Multiply by the Conversion Factor: To convert attojoule to kilojoule, multiply the selected aJ value by 1e-21. This factor is essential for accurately converting from a larger unit (aJ) to a much smaller unit (kJ).
- Illustration of Multiplication:
- 1 aJ = 1e-21 kJ
- 10 aJ = 0.010 kJ
- 100 aJ = 1e-19 kJ
- Find the Conversion Result: The result of this multiplication is your converted value in kilojoule unit. This represents the same energy but in a different unit.
- Save Your Kilojoule Value: After converting, remember to save the result. This value represents the energy you initially measured, now expressed in kilojoules.
- Alternative Method – Division: If you prefer not to multiply, you can achieve the same conversion by dividing the attojoule value by 1e+21. This alternative method also gives you the correct energy in kilojoules.
- Illustration of Division:
- kJ = aj ÷ 1e+21

Attojoule to Kilojoule Examples
Example 1:
Convert 0.9 Attojoule to Kilojoule.
Solution:
We know that one Attojoule is equivalent to 1e-21 Kilojoule.
Therefore,
0.9 aJ = 0.9 x 1e-21 kJ.
0.9 aJ = 9e-22 kJ.
Hence, 0.9 Attojoule is approximately equal to 9e-22 Kilojoule.
Example 2:
Convert 10 Attojoule to Kilojoule.
Solution:
We know that one Attojoule is equivalent to 1e-21 Kilojoule.
