What is Millijoule to Petajoule Conversion?
Millijoule (mJ) and petajoule (PJ) 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 millijoule to petajoule, knowing the exact conversion formula is essential.
MJ to pj Conversion Formula:
One Millijoule is equal to 1e-18 Petajoule.
Formula: 1 mJ = 1e-18 PJ
By using this conversion factor, you can easily convert any energy from millijoule to petajoule with precision.
How to Convert mJ to PJ?
Converting from mJ to PJ is a straightforward process. Follow these steps to ensure accurate conversions from millijoule to petajoule:
- Select the Millijoule Value: Start by determining the millijoule (mJ) value you want to convert into petajoule (PJ). This is your starting point.
- Multiply by the Conversion Factor: To convert millijoule to petajoule, multiply the selected mJ value by 1e-18. This factor is essential for accurately converting from a larger unit (mJ) to a much smaller unit (PJ).
- Illustration of Multiplication:
- 1 mJ = 1e-18 PJ
- 10 mJ = 1e-17 PJ
- 100 mJ = 1e-16 PJ
- Find the Conversion Result: The result of this multiplication is your converted value in petajoule unit. This represents the same energy but in a different unit.
- Save Your Petajoule Value: After converting, remember to save the result. This value represents the energy you initially measured, now expressed in petajoules.
- Alternative Method – Division: If you prefer not to multiply, you can achieve the same conversion by dividing the millijoule value by 1e+18. This alternative method also gives you the correct energy in petajoules.
- Illustration of Division:
- PJ = mj ÷ 1e+18

Millijoule to Petajoule Examples
Example 1:
Convert 0.7 Millijoule to Petajoule.
Solution:
We know that one Millijoule is equivalent to 1e-18 Petajoule.
Therefore,
0.7 mJ = 0.7 x 1e-18 PJ.
0.7 mJ = 7e-19 PJ.
Hence, 0.7 Millijoule is approximately equal to 7e-19 Petajoule.
Example 2:
Convert 6 Millijoule to Petajoule.
Solution:
We know that one Millijoule is equivalent to 1e-18 Petajoule.
Therefore,
6 mJ = 6 x 1e-18 PJ.
6 mJ = 6e-18 PJ.
Hence, 6 Millijoule is approximately equal to 6e-18 Petajoule.
Example 3:
Convert 18 Millijoule to Petajoule.
Solution:
We know that one Millijoule is equivalent to 1e-18 Petajoule.
Therefore,
18 mJ = 18 x 1e-18 PJ.
18 mJ = 1.8e-17 PJ.
Hence, 18 Millijoule is approximately equal to 1.8e-17 Petajoule.
Example 4:
