Electronvolt to Watt Hour (eV to Wh)
Convert eV to Wh — Energy converter
One electronvolt equals 4.450000e-23 Wh, so to convert electronvolts to watt-hours you multiply the value by 4.450000e-23. A electronvolt is smaller than a watt hour — going the other way, 1 Wh = 2.247191e+22 eV. For example, 10 eV = 4.450000e-22 Wh and 50 eV = 2.225000e-21 Wh.
1 eV = 4.450000e-23 Wh
Electronvolt to Watt Hour formula
1 Electronvolt = 4.450000e-23 Wh
Worked examples
- 25 eV = 1.112500e-21 Wh
- 100 eV = 4.450000e-21 Wh
