How to Convert Watt-Seconds to Kiloelectronvolts

To convert a measurement in watt-seconds to a measurement in kiloelectronvolts, multiply 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:

kiloelectronvolts = watt-seconds × 6.2415E+15

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

For example, here's how to convert 5 watt-seconds to kiloelectronvolts using the formula above.
kiloelectronvolts = (5 Ws × 6.2415E+15) = 3.1208E+16 keV

How Many Kiloelectronvolts Are in a Watt-Second?

There are 6.2415E+15 kiloelectronvolts in a watt-second, which is why we use this value in the formula above.

1 Ws = 6.2415E+15 keV

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

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]

What Is a Kiloelectronvolt?

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