What is Kilojoule to Attojoule Conversion?
Kilojoule (kJ) 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 kilojoule to attojoule, knowing the exact conversion formula is essential.
KJ to aj Conversion Formula:
One Kilojoule is equal to 1e+21 Attojoule.
Formula: 1 kJ = 1e+21 aJ
By using this conversion factor, you can easily convert any energy from kilojoule to attojoule with precision.
How to Convert kJ to aJ?
Converting from kJ to aJ is a straightforward process. Follow these steps to ensure accurate conversions from kilojoule to attojoule:
- Select the Kilojoule Value: Start by determining the kilojoule (kJ) value you want to convert into attojoule (aJ). This is your starting point.
- Multiply by the Conversion Factor: To convert kilojoule to attojoule, multiply the selected kJ value by 1e+21. This factor is essential for accurately converting from a larger unit (kJ) to a much smaller unit (aJ).
- Illustration of Multiplication:
- 1 kJ = 1e+21 aJ
- 10 kJ = 1e+22 aJ
- 100 kJ = 1e+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 kilojoule value by 1e-21. This alternative method also gives you the correct energy in attojoules.
- Illustration of Division:
- aJ = kj ÷ 1e-21

Kilojoule to Attojoule Examples
Example 1:
Convert 0.9 Kilojoule to Attojoule.
Solution:
We know that one Kilojoule is equivalent to 1e+21 Attojoule.
Therefore,
0.9 kJ = 0.9 x 1e+21 aJ.
0.9 kJ = 9e+20 aJ.
Hence, 0.9 Kilojoule is approximately equal to 9e+20 Attojoule.
Example 2:
Convert 10 Kilojoule to Attojoule.
Solution:
We know that one Kilojoule is equivalent to 1e+21 Attojoule.
Therefore,
10 kJ = 10 x 1e+21 aJ.
10 kJ = 1e+22 aJ.
Hence, 10 Kilojoule is approximately equal to 1e+22 Attojoule.
Example 3:
