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

Exajoule to Watt-second Examples
Example 1:
Convert 0.5 Exajoule to Watt-second.
Solution:
We know that one Exajoule is equivalent to 1e+18 Watt-second.
Therefore,
0.5 EJ = 0.5 x 1e+18 Watt-second.
0.5 EJ = 5e+17 Watt-second.
Hence, 0.5 Exajoule is approximately equal to 5e+17 Watt-second.
Example 2:
Convert 5 Exajoule to Watt-second.
Solution:
We know that one Exajoule is equivalent to 1e+18 Watt-second.
Therefore,
5 EJ = 5 x 1e+18 Watt-second.
5 EJ = 5e+18 Watt-second.
Hence, 5 Exajoule is approximately equal to 5e+18 Watt-second.
Example 3:
Convert 90 Exajoule to Watt-second.
