How to Convert Kiloelectronvolts to Megawatt-Hours

To convert a measurement in kiloelectronvolts to a measurement in megawatt-hours, multiply the energy by the following conversion ratio: 4.4505E-26 megawatt-hours/kiloelectronvolt.

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

megawatt-hours = kiloelectronvolts × 4.4505E-26

The energy in megawatt-hours is equal to the energy in kiloelectronvolts multiplied by 4.4505E-26.

For example, here's how to convert 5.0E+25 kiloelectronvolts to megawatt-hours using the formula above.
megawatt-hours = (5.0E+25 keV × 4.4505E-26) = 2.225245 MWh

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

What Is a Kiloelectronvolt?

Kiloelectronvolts can be abbreviated as keV; for example, 1 kiloelectronvolt can be written as 1 keV.

What Is a Megawatt-Hour?

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]
