How to Convert Watt-hours to Megaelectronvolts

To convert a watt-hour measurement to a megaelectronvolt measurement, multiply the energy by the conversion ratio.

Since one watt-hour is equal to 2.2469E+16 megaelectronvolts, you can use this simple formula to convert:

megaelectronvolts = watt-hours × 2.2469E+16

The energy in megaelectronvolts is equal to the watt-hours multiplied by 2.2469E+16.

For example, here's how to convert 5 watt-hours to megaelectronvolts using the formula above.
5 Wh = (5 × 2.2469E+16) = 1.1235E+17 MeV

How Many Megaelectronvolts are in a Watt-hour?

There are 2.2469E+16 megaelectronvolts in a watt-hour, which is why we use this value in the formula above.

1 Wh = 2.2469E+16 MeV

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


The watt-hour is a measure of electrical energy equal to one watt of power over a one hour period.

Watt-hours are usually abbreviated as Wh, although the formally adopted expression is W·h. The abbreviation W h is also sometimes used. For example, 1 watt-hour can be written as 1 Wh, 1 W·h, or 1 W 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]


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