What does one kilowatt-second represent?

One kilowatt-second is the energy delivered by a 1 kilowatt power source running for one second, equal to one kilojoule or 1000 joules.

Why convert kilowatt-seconds to electron-volts?

Converting kilowatt-seconds to electron-volts allows relating macroscopic energy pulses to atomic and subatomic energy scales used in physics and electronics.

Are electron-volts suitable for large energy values?

Electron-volts are typically used for microscopic energies; large energy values converted into eV result in very large numbers expressed using scientific notation.
