## How to Convert Electronvolts to Watt-Hours

To convert a measurement in electronvolts to a measurement in watt-hours, multiply the energy by the following conversion ratio: 4.4505E-23 watt-hours/electronvolt.

Since one electronvolt is equal to 4.4505E-23 watt-hours, you can use this simple formula to convert:

watt-hours = electronvolts × 4.4505E-23

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

**For example,**here's how to convert 5.0E+22 electronvolts to watt-hours using the formula above.

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

## What Is an Electronvolt?

An electronvolt is the amount of energy required to accelerate an electron through a difference in electric potential of one volt in vacuum.
One electronvolt is equal to the charge of 1.602176634 × 10^{−19} C, and is equal to the energy of 1.602176634 × 10^{−19} Joules.^{[1]}

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.

## What Is a Watt-Hour?

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.^{[2]}
