What units does this converter transform?

It converts energy units from watt-seconds (W·s), equivalent to joules, into kiloelectron-volts (keV), used in atomic and nuclear physics.

Why use kiloelectron-volts instead of joules in some fields?

Kiloelectron-volts express energies at atomic and particle scales, making them more suitable for fields like nuclear physics and medical imaging.

Are conversions exact between these units?

While based on defined constants, minor rounding differences can occur, affecting precision in sensitive applications.
