How to Convert Megaelectronvolts to Kilowatt-Hours

To convert a measurement in megaelectronvolts to a measurement in kilowatt-hours, multiply the energy by the following conversion ratio: 4.4505E-20 kilowatt-hours/megaelectronvolt.

Since one megaelectronvolt is equal to 4.4505E-20 kilowatt-hours, you can use this simple formula to convert:

kilowatt-hours = megaelectronvolts × 4.4505E-20

The energy in kilowatt-hours is equal to the energy in megaelectronvolts multiplied by 4.4505E-20.

For example, here's how to convert 5.0E+19 megaelectronvolts to kilowatt-hours using the formula above.
kilowatt-hours = (5.0E+19 MeV × 4.4505E-20) = 2.225245 kWh

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

What Is a Megaelectronvolt?

Megaelectronvolts can be abbreviated as MeV; for example, 1 megaelectronvolt can be written as 1 MeV.

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.[1]
