To convert a measurement in watt-seconds to a measurement in electronvolts, multiply the energy by the following conversion ratio: 6.2415E+18 electronvolts/watt-second.

Since one watt-second is equal to 6.2415E+18 electronvolts, you can use this simple formula to convert:

electronvolts = watt-seconds × 6.2415E+18

The energy in electronvolts is equal to the energy in watt-seconds multiplied by 6.2415E+18.

For example, here's how to convert 5 watt-seconds to electronvolts using the formula above.
electronvolts = (5 Ws × 6.2415E+18) = 3.1208E+19 eV

How Many Electronvolts Are in a Watt-Second?

There are 6.2415E+18 electronvolts in a watt-second, which is why we use this value in the formula above.

1 Ws = 6.2415E+18 eV

Watt-seconds and electronvolts 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 an Electronvolt?

An electronvolt is the amount of energy required to accelerate an electron through a difference in electric potential of one volt in vacuum. One electronvolt is equal to the charge of 1.602176634 × 10−19 C, and is equal to the energy of 1.602176634 × 10−19 Joules.[2]

Electronvolts can be abbreviated as eV; for example, 1 electronvolt can be written as 1 eV.

Energy in electronvolts can be expressed using the following formula: E = qV

The energy E in electronvolts is equal to the electric charge q in elementary charge times the potential difference V in volts.
