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

Kilowatt-second to Femtojoule Examples
Example 1:
Convert 0.7 Kilowatt-second to Femtojoule.
Solution:
We know that one Kilowatt-second is equivalent to 1e+18 Femtojoule.
Therefore,
0.7 kWs = 0.7 x 1e+18 fJ.
0.7 kWs = 7e+17 fJ.
Hence, 0.7 Kilowatt-second is approximately equal to 7e+17 Femtojoule.
Example 2:
Convert 4 Kilowatt-second to Femtojoule.
Solution:
We know that one Kilowatt-second is equivalent to 1e+18 Femtojoule.
Therefore,
4 kWs = 4 x 1e+18 fJ.
4 kWs = 4e+18 fJ.
Hence, 4 Kilowatt-second is approximately equal to 4e+18 Femtojoule.
Example 3:
Convert 25 Kilowatt-second to Femtojoule.
Solution:
We know that one Kilowatt-second is equivalent to 1e+18 Femtojoule.
Therefore,
25 kWs = 25 x 1e+18 fJ.
25 kWs = 2.5e+19 fJ.
Hence, 25 Kilowatt-second is approximately equal to 2.5e+19 Femtojoule.
Example 4:
Convert 693 Kilowatt-second to Femtojoule.
