How to Convert Watt-Hours to Kiloelectronvolts

To convert a measurement in watt-hours to a measurement in kiloelectronvolts, multiply the energy by the following conversion ratio: 2.2469E+19 kiloelectronvolts/watt-hour.

Since one watt-hour is equal to 2.2469E+19 kiloelectronvolts, you can use this simple formula to convert:

kiloelectronvolts = watt-hours × 2.2469E+19

The energy in kiloelectronvolts is equal to the energy in watt-hours multiplied by 2.2469E+19.

For example, here's how to convert 5 watt-hours to kiloelectronvolts using the formula above.
kiloelectronvolts = (5 Wh × 2.2469E+19) = 1.1235E+20 keV

How Many Kiloelectronvolts Are in a Watt-Hour?

There are 2.2469E+19 kiloelectronvolts in a watt-hour, which is why we use this value in the formula above.

1 Wh = 2.2469E+19 keV

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

What Is a Watt-Hour?

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]

What Is a Kiloelectronvolt?

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