## How to Convert Kiloelectronvolts to Watt-Seconds

To convert a measurement in kiloelectronvolts to a measurement in watt-seconds, divide the energy by the following conversion ratio: 6.2415E+15 kiloelectronvolts/watt-second.

Since one watt-second is equal to 6.2415E+15 kiloelectronvolts, you can use this simple formula to convert:

watt-seconds = kiloelectronvolts ÷ 6.2415E+15

The energy in watt-seconds is equal to the energy in kiloelectronvolts divided by 6.2415E+15.

For example, here's how to convert 5.0E+15 kiloelectronvolts to watt-seconds using the formula above.
watt-seconds = (5.0E+15 keV ÷ 6.2415E+15) = 0.801088 Ws

## What Is a Kiloelectronvolt?

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

## What Is a Watt-Second?

The watt-second is a measure of electrical energy equal to one watt of power over a one second period. One watt-second is equal to 1/3,600 of a watt-hour or one joule.

Watt-seconds are usually abbreviated as Ws, although the formally adopted expression is W·s. The abbreviation W s is also sometimes used. For example, 1 watt-second can be written as 1 Ws, 1 W·s, or 1 W s.

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]
