How to Convert Electronvolts to Watt-hours

To convert a electronvolt measurement to a watt-hour measurement, multiply the energy by the conversion ratio. One electronvolt is equal to 4.4505E-23 watt-hours, so use this simple formula to convert:

watt-hours = electronvolts × 4.4505E-23

The energy in watt-hours is equal to the electronvolts multiplied by 4.4505E-23.

For example, here's how to convert 5 electronvolts to watt-hours using the formula above.
5 eV = (5 × 4.4505E-23) = 2.2252E-22 Wh

Electronvolts and watt-hours are both units used to measure energy. Keep reading to learn more about each unit of measure.


The electronvolt is a unit of energy used in physics, most commonly in electrostatic particle accelerator sciences.

Electronvolts can be abbreviated as eV, for example 1 electronvolt can be written as 1 eV.

Energy in electronvolts can be expressed using the following formula: E = qV

The energy E in electronvolts is equal to the electric charge q in elementary charge times the potential difference V in volts.


The watt-hour is a measure of electrical energy equal to one watt of power over a one hour period.

Watt-hours can be abbreviated as Wh, for example 1 watt-hour can be written as 1 Wh.
