What is a kilocalorie (th)/hour?

It is a power unit representing one thermochemical kilocalorie of energy transferred per hour, measuring heat flow rate.

A milliwatt is one thousandth of a watt, the SI unit for power, commonly used for low-power electronic or optical measurements.

Why convert kilocalorie (th)/hour to milliwatt?

Conversion enables comparison and integration of thermal power measurements with electronic power ratings commonly expressed in milliwatts.
