Understanding Watt-Seconds and Electronvolts
What is a Watt-Second?
A watt-second (Ws) is a unit of energy equal to one watt of power sustained for one second. It's equivalent to one joule and represents the amount of energy needed to power a one-watt device for exactly one second.
What is an Electronvolt?
An electronvolt (eV) is the energy gained by an electron moving across an electric potential difference of one volt. It's commonly used in atomic physics and represents a very small amount of energy (1.602176634 × 10⁻¹⁹ joules).
Conversion Formula
To convert watt-seconds to electronvolts, use the following formula:
Electronvolts = Watt-seconds × 6.2415E+18
