What is Petajoule to Millijoule Conversion?
Petajoule (PJ) and millijoule (mJ) 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 petajoule to millijoule, knowing the exact conversion formula is essential.
PJ to mj Conversion Formula:
One Petajoule is equal to 1e+18 Millijoule.
Formula: 1 PJ = 1e+18 mJ
By using this conversion factor, you can easily convert any energy from petajoule to millijoule with precision.
How to Convert PJ to mJ?
Converting from PJ to mJ is a straightforward process. Follow these steps to ensure accurate conversions from petajoule to millijoule:
- Select the Petajoule Value: Start by determining the petajoule (PJ) value you want to convert into millijoule (mJ). This is your starting point.
- Multiply by the Conversion Factor: To convert petajoule to millijoule, multiply the selected PJ value by 1e+18. This factor is essential for accurately converting from a larger unit (PJ) to a much smaller unit (mJ).
- Illustration of Multiplication:
- 1 PJ = 1e+18 mJ
- 10 PJ = 1e+19 mJ
- 100 PJ = 1e+20 mJ
- Find the Conversion Result: The result of this multiplication is your converted value in millijoule unit. This represents the same energy but in a different unit.
- Save Your Millijoule Value: After converting, remember to save the result. This value represents the energy you initially measured, now expressed in millijoules.
- Alternative Method – Division: If you prefer not to multiply, you can achieve the same conversion by dividing the petajoule value by 1e-18. This alternative method also gives you the correct energy in millijoules.
- Illustration of Division:
- mJ = pj ÷ 1e-18

Petajoule to Millijoule Examples
Example 1:
Convert 0.9 Petajoule to Millijoule.
Solution:
We know that one Petajoule is equivalent to 1e+18 Millijoule.
Therefore,
0.9 PJ = 0.9 x 1e+18 mJ.
0.9 PJ = 9e+17 mJ.
Hence, 0.9 Petajoule is approximately equal to 9e+17 Millijoule.
Example 2:
Convert 8 Petajoule to Millijoule.
Solution:
We know that one Petajoule is equivalent to 1e+18 Millijoule.
Therefore,
8 PJ = 8 x 1e+18 mJ.
8 PJ = 8e+18 mJ.
Hence, 8 Petajoule is approximately equal to 8e+18 Millijoule.
Example 3:
Convert 44 Petajoule to Millijoule.
Solution:
We know that one Petajoule is equivalent to 1e+18 Millijoule.
Therefore,
