What is an attojoule used to measure?

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

Why convert attojoules to megawatt-hours?

Converting attojoules to megawatt-hours allows comparison of ultra-small energy scales with large-scale energy units used in utilities and power generation.

Are the megawatt-hour values from attojoules easy to interpret?

Due to the huge size difference, converted megawatt-hour values are extremely tiny and may be challenging to interpret in typical large-energy scenarios.
