# Kiloelectronvolts to Kilowatt-hours Conversion

Enter the energy in kiloelectronvolts below to get the value converted to kilowatt-hours.

Results in Kilowatt-hours: 1 keV = 4.4505E-23 kWh

## How to Convert Kiloelectronvolts to Kilowatt-hours

To convert a kiloelectronvolt measurement to a kilowatt-hour measurement, multiply the energy by the conversion ratio. One kiloelectronvolt is equal to 4.4505E-23 kilowatt-hours, so use this simple formula to convert:

kilowatt-hours = kiloelectronvolts × 4.4505E-23

The energy in kilowatt-hours is equal to the kiloelectronvolts multiplied by 4.4505E-23.

For example, here's how to convert 5.0E+22 kiloelectronvolts to kilowatt-hours using the formula above.
5.0E+22 keV = (5.0E+22 × 4.4505E-23) = 2.225245 kWh

## Kiloelectronvolts

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

## Kilowatt-hours

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.
