What Is This Tool?
This unit converter transforms thermal conductivity measurements expressed in kilocalorie (IT) per hour per meter per degree Celsius into Btu (IT) inch per hour per square foot per degree Fahrenheit. It supports engineers, architects, and energy consultants by facilitating conversions between metric-based non-SI units and imperial units commonly used in North America.

2 kilocalorie (IT)/hour/meter/°C converts to approximately 16.1273 Btu (IT) inch/hour/sq. foot/°F
-
0.5 kilocalorie (IT)/hour/meter/°C converts to approximately 4.0318 Btu (IT) inch/hour/sq. foot/°F
Common Use Cases
-
Specifying thermal conductivity for building insulation and construction materials in HVAC and energy-loss calculations
-
Comparing heat-transfer characteristics of metals, ceramics, and composites in older or regional engineering contexts using kcal units
-
Sizing heat exchangers and piping designs where legacy data is in kilocalorie (IT)/hour/meter/°C
-
Translating metric thermal conductivity values to imperial units for North American building code compliance
-
Calculating steady-state heat transfer through building elements like walls and roofs
Tips & Best Practices
-
Verify unit consistency and conversion assumptions before applying results
-
Consider differences in measurement thickness (meters vs. inches) and temperature scales (°C vs. °F)
-
Ensure steady-state heat flow conditions to maintain conversion validity
-
Cross-check conversions when comparing regional or legacy material data
-
Use the tool for preliminary estimates and supplement with detailed engineering analysis as needed
Limitations
-
Conversion depends on steady-state thermal conduction and uniform material properties assumptions
-
Differences in unit thickness and temperature scales require careful application of conversion factors
-
Material and regional standard variations can affect data consistency
-
Not suitable for dynamic or transient heat transfer scenarios
-
Users should confirm compatibility with local codes and measurement conventions
Frequently Asked Questions
-
What does kilocalorie (IT)/hour/meter/°C measure?
-
It measures thermal conductivity as the steady heat flow in kilocalories per hour through a one-meter thickness of material with a one-degree Celsius temperature difference.
-
Why convert to Btu (IT) inch/hour/sq. foot/°F?
-
Converting to this unit allows compatibility with North American building and HVAC standards that use imperial units for specifying insulation and material thermal properties.
-
Can I use this converter for non-steady heat flow?
-
No, the conversion assumes steady-state heat flow and uniform material properties, so it is not accurate for transient or varying heat transfer conditions.
Key Terminology
