What is Electron-volt to Watt-hour Conversion?
Electron-volt (eV) and watt-hour (Wh) 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 electron-volt to watt-hour, knowing the exact conversion formula is essential.
EV to wh Conversion Formula:
One Electron-volt is equal to 4.005442e-23 Watt-hour.
Formula: 1 eV = 4.005442e-23 Wh
By using this conversion factor, you can easily convert any energy from electron-volt to watt-hour with precision.
How to Convert eV to Wh?
Converting from eV to Wh is a straightforward process. Follow these steps to ensure accurate conversions from electron-volt to watt-hour:
- Select the Electron-volt Value: Start by determining the electron-volt (eV) value you want to convert into watt-hour (Wh). This is your starting point.
- Multiply by the Conversion Factor: To convert electron-volt to watt-hour, multiply the selected eV value by 4.005442e-23. This factor is essential for accurately converting from a larger unit (eV) to a much smaller unit (Wh).
- Illustration of Multiplication:
- 1 eV = 4.005442e-23 Wh
- 10 eV = Wh
- 100 eV = Wh
- Find the Conversion Result: The result of this multiplication is your converted value in watt-hour unit. This represents the same energy but in a different unit.
- Save Your Watt-hour Value: After converting, remember to save the result. This value represents the energy you initially measured, now expressed in watt-hours.
- Alternative Method – Division: If you prefer not to multiply, you can achieve the same conversion by dividing the electron-volt value by 2.246943e+22. This alternative method also gives you the correct energy in watt-hours.
- Illustration of Division:
- Wh = ev ÷ 2.246943e+22
