How to Convert Electronvolts to Kilowatt-Hours

To convert a measurement in electronvolts to a measurement in kilowatt-hours, multiply the energy by the following conversion ratio: 4.4505E-26 kilowatt-hours/electronvolt.

Since one electronvolt is equal to 4.4505E-26 kilowatt-hours, you can use this simple formula to convert:

kilowatt-hours = electronvolts × 4.4505E-26

The energy in kilowatt-hours is equal to the energy in electronvolts multiplied by 4.4505E-26.

For example, here's how to convert 5.0E+25 electronvolts to kilowatt-hours using the formula above.
kilowatt-hours = (5.0E+25 eV × 4.4505E-26) = 2.225245 kWh

Electronvolts and kilowatt-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 Kilowatt-Hour?

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.[2]
