Tips & Best Practices
-
Ensure correct unit selection to maintain accurate conversions
-
Use the tool to translate legacy thermal data into SI units for consistency
-
Apply conversions only when steady-state conditions apply as assumed by the units
-
Be aware of material homogeneity and temperature scale differences in interpretations
Limitations
-
Differences in unit definitions and temperature scales may affect accuracy
-
Conversions assume steady-state heat flow and homogeneous material properties
-
Not intended for dynamic or transient thermal conductivity evaluations
Frequently Asked Questions
-
What does kilocalorie (IT)/hour/meter/°C measure?
-
It measures thermal conductivity based on heat flow of one kilocalorie per hour through a meter thickness with a temperature difference of one degree Celsius.
-
Why convert to watt/meter/K?
-
Because watt/meter/K is the SI unit for thermal conductivity, widely used in modern engineering to ensure compatibility and standardization.
-
Can this converter be used for non-steady-state conditions?
-
No, the units assume steady-state heat flow, so the converter is intended for steady-state thermal conductivity values.
