What is Gigajoule to Joule Conversion?
Gigajoule (GJ) and joule (J) 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 gigajoule to joule, knowing the exact conversion formula is essential.
GJ to j Conversion Formula:
One Gigajoule is equal to 1e+9 Joule.
Formula: 1 GJ = 1e+9 J
By using this conversion factor, you can easily convert any energy from gigajoule to joule with precision.
How to Convert GJ to J?
Converting from GJ to J is a straightforward process. Follow these steps to ensure accurate conversions from gigajoule to joule:
- Select the Gigajoule Value: Start by determining the gigajoule (GJ) value you want to convert into joule (J). This is your starting point.
- Multiply by the Conversion Factor: To convert gigajoule to joule, multiply the selected GJ value by 1e+9. This factor is essential for accurately converting from a larger unit (GJ) to a much smaller unit (J).
- Illustration of Multiplication:
- 1 GJ = 1e+9 J
- 10 GJ = 1e+10 J
- 100 GJ = 1e+11 J
- Find the Conversion Result: The result of this multiplication is your converted value in joule unit. This represents the same energy but in a different unit.
- Save Your Joule Value: After converting, remember to save the result. This value represents the energy you initially measured, now expressed in joules.
- Alternative Method – Division: If you prefer not to multiply, you can achieve the same conversion by dividing the gigajoule value by 1e-9. This alternative method also gives you the correct energy in joules.
- Illustration of Division:
- J = gj ÷ 1e-9

Gigajoule to Joule Examples
Example 1:
Convert 0.8 Gigajoule to Joule.
Solution:
We know that one Gigajoule is equivalent to 1e+9 Joule.
Therefore,
0.8 GJ = 0.8 x 1e+9 J.
0.8 GJ = 800000000 J.
Hence, 0.8 Gigajoule is approximately equal to 800000000 Joule.
Example 2:
Convert 5 Gigajoule to Joule.
Solution:
We know that one Gigajoule is equivalent to 1e+9 Joule.
Therefore,
5 GJ = 5 x 1e+9 J.
5 GJ = 5e+9 J.
Hence, 5 Gigajoule is approximately equal to 5e+9 Joule.
Example 3:
Convert 68 Gigajoule to Joule.
Solution:
We know that one Gigajoule is equivalent to 1e+9 Joule.
Therefore,
68 GJ = 68 x 1e+9 J.
68 GJ = 6.8e+10 J.
Hence, 68 Gigajoule is approximately equal to 6.8e+10 Joule.
Example 4:
Convert 339 Gigajoule to Joule.
