Discover the ease of converting electron-volts to watt-seconds with our precise eV to Ws tool, tailored for enthusiasts and professionals alike.
An electron-volt (eV) is a unit of energy equal to approximately 1.602×10⁻¹⁹ joules. It is the amount of kinetic energy gained by a single electron when it accelerates through an electric potential difference of one volt. It's a convenient unit of energy used in the field of particle physics and quantum mechanics, where dealing with extremely small energy scales is routine.
Definition of Watt-secondA watt-second (Ws) is a derived unit of energy equivalent to one joule. It represents the amount of energy expended when a one-watt device operates for one second. This unit is foundational in understanding and calculating energy consumption and generation in various fields, including electrical engineering and energy management.
