How to Convert Watt-Hours to Electronvolts

To convert a measurement in watt-hours to a measurement in electronvolts, multiply the energy by the following conversion ratio: 2.2469E+22 electronvolts/watt-hour.

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 energy in watt-hours multiplied by 2.2469E+22.

For example, here's how to convert 5 watt-hours to electronvolts using the formula above.
electronvolts = (5 Wh × 2.2469E+22) = 1.1235E+23 eV

How Many Electronvolts Are in a Watt-Hour?

There are 2.2469E+22 electronvolts in a watt-hour, which is why we use this value in the formula above.

1 Wh = 2.2469E+22 eV

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

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.[1]

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.[2]

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.
