Legacy kilocalorie units can cause confusion if usage is not well documented
Frequently Asked Questions
-
Why convert W/(m*K) to kilocalorie (IT)/hour/meter/°C?
-
Converting these units helps compare and use thermal conductivity data across different measurement standards, especially in HVAC and older engineering materials.
-
Is the difference between kelvin and Celsius significant in this conversion?
-
No, the difference between kelvin and degrees Celsius is negligible when calculating conduction thermal conductivity.
-
Can this conversion be used for modern engineering designs?
-
Yes, but it is mainly useful for legacy data or regional unit preferences in thermal conductivity.
Key Terminology
-
Watt per meter per kelvin (W/(m·K))
-
The SI derived unit of thermal conductivity indicating heat transfer rate per meter thickness with a temperature gradient of one kelvin.
-
Kilocalorie (IT)/hour/meter/°C
-
A unit of thermal conductivity representing heat flow of one kilocalorie per hour per meter for a 1 °C temperature difference across the material thickness.
