What is a microjoule used to measure?

A microjoule quantifies very small amounts of energy, such as pulse energy in lasers, energy in small capacitors, and mechanical work in micro-scale devices.

Why convert microjoules to watt-hours?

Converting helps express tiny energy quantities in terms of electrical energy over time, making it easier to integrate micro-scale measurements into broader energy analysis.

Is this conversion useful for typical household electricity bills?

No, due to the extremely small magnitude of microjoules, this conversion is mainly relevant for precise scientific and engineering tasks, not standard billing.
