Electronvolts to watt-hour Conversion
1 electronvolts (eV) is equal to 0.0000000000000000000000445049065 watt-hour (W⋅hr).
1 eV = 0.0000000000000000000000445049065 W⋅hr
or
1 W⋅hr = 22469432670000000000000 eV
Formula
To convert a energy from electronvolts (eV) to watt-hour (W⋅hr), divide the energy in electronvolts by 22469432670000000000000
e(W⋅hr) = e(eV) / 22469432670000000000000
Frequently asked questions
How do I convert electronvolts to watt-hour?
Divide the value in electronvolts by 22469432670000000000000 to get the result in watt-hour. For example, 5 eV ÷ 22469432670000000000000 = 0 W⋅hr.
How many watt-hour are in 1 electronvolts?
1 electronvolts (eV) is equal to 0 watt-hour (W⋅hr).
How do I convert watt-hour back to electronvolts?
Use the inverse operation: multiply the value in watt-hour by 22469432670000000000000 to get the result in electronvolts.
How accurate is the electronvolts to watt-hour conversion?
The converter multiplies by the conversion factor 22469432670000000000000 and rounds the result to 9 decimal places by default. You can increase or reduce the precision with the digits option on this page.
