What Is This Tool?
This converter transforms thermal conductivity measurements from the metric unit kilocalorie (th)/hour/meter/°C to the Imperial unit Btu (th) inch/second/sq. foot/°F. It is useful in translating material properties between different unit systems commonly used in building engineering, HVAC, and industrial heat transfer.

Frequently Asked Questions
-
What does kilocalorie (th)/hour/meter/°C measure?
-
It measures thermal conductivity as the heat flow in kilocalories per hour through a meter thick material for a one degree Celsius temperature difference.
-
Why convert to Btu (th) inch/second/sq. foot/°F?
-
Because it allows thermal conductivity data to be expressed in US customary (Imperial) units commonly used in HVAC and building calculations.
-
Are the conversion results exact?
-
Results depend on consistent temperature and thickness parameters and rounding in conversion constants, so slight variations can occur.
