Frequently Asked Questions
-
What does Btu (th) foot/hour/sq. foot/°F represent?
-
It is a thermal conductivity unit measuring heat transfer rate through a material in imperial units, specifying heat flow per hour through a 1-foot thickness and 1 square-foot area with a 1 °F temperature difference.
-
Why convert to calorie (th)/second/cm/°C?
-
This unit is used in older cgs-based engineering references and heat flow measurements, helping integrate legacy data with modern SI-based thermal calculations.
-
Can this converter handle other unit types?
-
No, this tool specifically converts thermal conductivity from Btu (th) foot/hour/sq. foot/°F to calorie (th)/second/cm/°C only.
