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 material one meter thick with a temperature difference of one degree Celsius.
-
Why convert to Btu (IT) foot/hour/sq. foot/°F?
-
This conversion enables consistent comparison and analysis of thermal properties between metric and Imperial units commonly used in building construction and HVAC systems.
-
Can this tool handle all thermal conductivity materials?
-
The tool converts based on steady-state heat conduction and assumes uniform material properties; variations due to environmental factors are not included.
