What does a microwatt (µW) measure?

A microwatt (µW) quantifies extremely small power levels, typically electrical or optical, equal to one millionth of a watt.

Where is calorie (th)/hour commonly used?

Calorie (th)/hour is used to measure thermal power rates in applications such as calorimetry, metabolic heat calculations, and low-level heat transfer.

Can I convert transient power values using this tool?

No, the conversion is designed for steady-state power conditions and may not accurately represent transient effects.
