Tips & Best Practices
-
Carefully verify units before converting to avoid errors from differing temperature scales.
-
Use steady-state and homogeneous material assumption for best correspondence with conversion.
-
Cross-check converted values when using legacy data with rounding limitations.
-
Apply converted thermal conductivity to correctly specify insulation resistance (R-value).
Limitations
-
Temperature scale differences (°C versus °F) require careful attention to avoid misinterpretation.
-
Assumes steady-state heat flow and consistent material properties; real-world variations may impact accuracy.
-
Precision may be affected by rounding or limitations of original data and instruments.
Frequently Asked Questions
-
Why convert thermal conductivity from calorie (th)/second/cm/°C to Btu (th) inch/hour/sq. foot/°F?
