What is a kilojoule used for?

A kilojoule measures energy commonly used in nutrition, chemical thermodynamics, and engineering to quantify heat, work, and energy transfer.

Why convert kilojoules to electron-volts?

Conversion is useful for translating macroscopic energy amounts into atomic and subatomic scales, which are common in physics, materials science, and semiconductor research.

Are there any challenges when converting large kilojoule values to electron-volts?

Yes, the resulting electron-volt values can be very large, making some calculations unwieldy and potentially affecting precision.
