How to Convert Kilowatt-hours to Electronvolts

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

Since one kilowatt-hour is equal to 2.2469E+25 electronvolts, you can use this simple formula to convert:

electronvolts = kilowatt-hours × 2.2469E+25

The energy in electronvolts is equal to the kilowatt-hours multiplied by 2.2469E+25.

For example, here's how to convert 5 kilowatt-hours to electronvolts using the formula above.
5 kWh = (5 × 2.2469E+25) = 1.1235E+26 eV

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


A kilowatt-hour is a measure of electrical energy equal to one kilowatt, or 1,000 watts, of power over a one hour period. Kilowatt-hours are a measure of electrical work performed over a period of time, and are often used as a way of measuring energy usage by electric companies.

Kilowatt-hours are usually abbreviated as kWh, although the formally adopted expression is kW·h. The abbreviation kW h is also sometimes used. For example, 1 kilowatt-hour can be written as 1 kWh, 1 kW·h, or 1 kW 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]


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.
