How to Convert Electronvolts to Megawatt-hours

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

Since one electronvolt is equal to 4.4505E-29 megawatt-hours, you can use this simple formula to convert:

megawatt-hours = electronvolts × 4.4505E-29

The energy in megawatt-hours is equal to the electronvolts multiplied by 4.4505E-29.

For example, here's how to convert 5.0E+28 electronvolts to megawatt-hours using the formula above.
5.0E+28 eV = (5.0E+28 × 4.4505E-29) = 2.225245 MWh

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


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.


A megawatt-hour is a measure of electrical energy equal to one megawatt, or 1,000,000 watts, of power over a one hour period. Megawatt-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.

Megawatt-hours are usually abbreviated as MWh, although the formally adopted expression is MW·h. The abbreviation MW h is also sometimes used. For example, 1 megawatt-hour can be written as 1 MWh, 1 MW·h, or 1 MW 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]
