Examples
-
1 kcal/(h·m·°C) converts to approximately 0.67197 Btu/(h·ft·°F).
-
5 kcal/(h·m·°C) converts to approximately 3.35985 Btu/(h·ft·°F).
Common Use Cases
-
Determining thermal conductivity of insulation materials in building walls, roofs, and windows.
-
Evaluating heat transfer through pipes, ducts, or heat exchanger walls in HVAC systems.
-
Converting legacy or regional technical data between calorie-based and Btu-based units for engineering design.
-
Conducting thermal conduction engineering calculations using imperial units.
Tips & Best Practices
-
Confirm the temperature difference units and ensure consistency when using conversion results.
-
Apply the tool for steady-state, one-dimensional heat conduction scenarios.
-
Use the converted values alongside recognized standards for insulation materials and building codes.
-
Be cautious when working with complex geometry or transient heat transfer conditions as additional analysis may be needed.
Limitations
-
Minor discrepancies may arise due to differences in temperature scales (°C vs. °F) and measurement standards.
-
The conversion is only valid for thermal conductivity properties, not for heat capacity or other thermal measures.
-
Assumes steady-state, one-dimensional conduction and doesn’t account for complex heat transfer conditions.
Frequently Asked Questions
-
What does kilocalorie (th)/hour/meter/°C represent?
-
It is a unit of thermal conductivity expressing heat flow in kilocalories per hour through one meter thickness with a one degree Celsius temperature difference.
-
What is Btu (th) foot/hour/sq. foot/°F used for?
-
This unit quantifies heat transfer rate in Btu per hour through a 1-foot thickness and 1 square-foot area for a 1 °F temperature difference, commonly used in building and HVAC applications with imperial units.
-
Why do I need to convert between these two units?
-
Converting helps translate thermal conductivity data between metric and imperial systems, enabling accurate heat transfer calculations across regional or legacy standards.
