What is an attojoule used for?

Attojoule is used to express extremely small energy amounts relevant in atomic, molecular, and single-photon scales, as well as in nanoscale and quantum device energy measurements.

Why convert attojoules to electron-volts?

Converting to electron-volts makes it easier to interpret energy values within atomic, molecular, semiconductor, and particle physics contexts where eV is a more common unit.

Are there any precision concerns in this conversion?

Yes, the small magnitude of attojoule energies and assumptions about ideal constants can introduce challenges in accuracy and precision.
