## How to Convert Watt-seconds to Electronvolts

To convert a watt-second measurement to an electronvolt measurement, multiply the energy by the conversion ratio.

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

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

**For example,**here's how to convert 5 watt-seconds to electronvolts using the formula above.

### 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.

## Watt-seconds

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]}

## Electronvolts

The electronvolt is a unit of energy used in physics, most commonly in electrostatic particle accelerator sciences.

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.
