How to Convert PWh to Ws?
Converting from PWh to Ws is a straightforward process. Follow these steps to ensure accurate conversions from petawatt-hour to watt-second:
- Select the Petawatt-hour Value: Start by determining the petawatt-hour (PWh) value you want to convert into watt-second (Ws). This is your starting point.
- Multiply by the Conversion Factor: To convert petawatt-hour to watt-second, multiply the selected PWh value by 2.16e+19. This factor is essential for accurately converting from a larger unit (PWh) to a much smaller unit (Ws).
- Illustration of Multiplication:
- 1 PWh = 2.16e+19 Ws
- 10 PWh = Ws
- 100 PWh = Ws
- 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 petawatt-hour value by 2.777778e-19. This alternative method also gives you the correct energy in watt-seconds.
- Illustration of Division:
- Ws = pwh ÷ 2.777778e-19
