Frequently Asked Questions
-
Why convert from calorie (th)/second/cm/°C to Btu (th) foot/hour/sq. foot/°F?
-
Converting these units allows using legacy or lab data in building or HVAC designs where imperial units like Btu/(h·ft·°F) are standard.
-
Is the conversion suitable for all thermal conductivity measurements?
-
It is intended for steady-state conduction data and may not apply to transient or non-homogeneous materials.
-
What should I watch for when converting units involving °C and °F?
-
Pay attention to the different temperature scales and ensure corresponding thickness and area units match the conversion assumptions.
