## How to Convert Watt-hours to Electronvolts

To convert a watt-hour measurement to an electronvolt measurement, multiply the energy by the conversion ratio. One watt-hour is equal to 2.2469E+22 electronvolts, so use this simple formula to convert:

The energy in electronvolts is equal to the watt-hours multiplied by 2.2469E+22.

**For example,**here's how to convert 5 watt-hours to electronvolts using the formula above.

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

## Watt-hours

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

Watt-hours are usually abbreviated as *Wh*, although the formally adopted expression is *W·h*. The abbreviation *W h* is also sometimes used. For example, 1 watt-hour can be written as 1 Wh, 1 W·h, or 1 W h.

In formal expressions, the centered dot (·) or space is used to separate units used to indicate multiplication in an expression and to avoid conflicting prefixes being misinterpreted as a unit symbol.^{[1]}

## Electronvolts

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.
