What does calorie (th)/hour measure?

Calorie (th)/hour measures the rate of heat transfer equivalent to one thermochemical calorie delivered each hour, representing thermal power.

Why convert calorie (th)/hour to microwatt?

Converting to microwatt allows expressing very small thermal power values in standard SI units commonly used in scientific and engineering fields.

Are there any conditions to keep in mind during conversion?

Yes, the conversion assumes steady-state heat transfer conditions and uniform thermal flow for accurate results.
