What Is This Tool?
This converter transforms thermal conductivity measurements from Btu (IT) foot/hour/sq. foot/°F, a unit commonly used in Imperial contexts, into calorie (IT)/second/cm/°C, a calorie-based unit utilized in legacy literature and certain non-SI applications. It supports tasks such as building insulation evaluation, HVAC modeling, and cross-system engineering analyses.

Performing steady-state heat conduction analyses for building materials in HVAC systems.
-
Converting material thermal data from Imperial units to calorie-based units found in historical or legacy references.
Tips & Best Practices
-
Always consider the difference in reference thickness and cross-sectional area between units during conversion.
-
Account for temperature scale differences (°F vs °C) when interpreting results.
-
Use this converter to enhance comparison of thermal properties across measurement systems.
Limitations
-
Units apply to different thickness and area sizes, requiring careful use in calculations.
-
Temperature scales differ, necessitating proper attention to °F and °C distinctions.
-
Calorie-based units are less frequent in modern SI environments, which can limit direct applicability.
Frequently Asked Questions
-
What does 1 Btu (IT) foot/hour/sq. foot/°F represent?
-
It represents the steady heat flow in Btu per hour through a 1-foot thick material layer with 1 square foot cross-section under a temperature difference of 1°F.
-
Why convert to calorie (IT)/second/cm/°C units?
-
Calorie (IT)/second/cm/°C is used in older or non-SI literature; converting helps compare and analyze thermal conductivities across different measurement systems.
-
Are there any considerations when converting with temperature differences?
-
Yes, as the original unit uses °F and the target uses °C, careful attention to these temperature scales is important during conversion.
