What is an attojoule used to measure?

An attojoule measures extremely small amounts of energy, such as those involved with single photons, nanoscale devices, and molecular processes.

How large is a gigajoule compared to an attojoule?

A gigajoule is vastly larger, equaling 10^9 joules, while an attojoule is 10^-18 joules, making the scale difference extremely significant.

Why convert attojoules to gigajoules?

Converting from attojoules to gigajoules helps relate tiny quantum-scale energy measurements to the large energy units used in industrial and engineering fields.
