## How to Convert Watt-hours to Electronvolts

To convert a watt-hour measurement to an electronvolt measurement, multiply the energy by the conversion ratio.

Since one watt-hour is equal to 2.2469E+22 electronvolts, you can use this simple formula to convert:

electronvolts = watt-hours × 2.2469E+22

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.
5 Wh = (5 × 2.2469E+22) = 1.1235E+23 eV

## 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.

## 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.
