What is Watt-second to Joule Conversion?
Watt-second (Ws) 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 watt-second to joule, knowing the exact conversion formula is essential.
Ws to j Conversion Formula:
One Watt-second is equal to 20 Joule.
Formula: 1 Ws = 20 J
By using this conversion factor, you can easily convert any energy from watt-second to joule with precision.
How to Convert Ws to J?
Converting from Ws to J is a straightforward process. Follow these steps to ensure accurate conversions from watt-second to joule:
- Select the Watt-second Value: Start by determining the watt-second (Ws) value you want to convert into joule (J). This is your starting point.
- Multiply by the Conversion Factor: To convert watt-second to joule, multiply the selected Ws value by 20. This factor is essential for accurately converting from a larger unit (Ws) to a much smaller unit (J).
- Illustration of Multiplication:
- 1 Ws = 20 J
- 10 Ws = J
- 100 Ws = 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 watt-second value by 1. This alternative method also gives you the correct energy in joules.
- Illustration of Division:
- J = ws ÷ 1
