Tips & Best Practices
-
Ensure consistent use of unit systems to avoid confusion between SI and non-SI units.
-
Use this tool to facilitate comparison between legacy data and modern measurements.
-
Check that steady-state conditions and uniform material properties apply for accurate interpretation.
-
Refer to unit definitions to understand the physical meaning of each unit.
-
Combine converted data with current standards for comprehensive analysis.
Limitations
-
Small discrepancies may arise due to differences in unit definitions and temperature scales.
-
Assumes steady-state heat flow and uniform material characteristics.
-
Potential confusion can occur when mixing non-SI units like kcal and cal with SI units without clarification.
Frequently Asked Questions
-
What does kilocalorie (IT)/hour/meter/°C measure?
-
It measures the steady-state heat flow of one kilocalorie (International Table) per hour through a one-meter thickness of material with a temperature difference of 1 °C.
-
When should I use calorie (IT)/second/cm/°C?
-
This unit is useful when reporting or comparing thermal conductivities from older literature or when dealing with finer material dimensions and faster thermal processes.
-
Why convert between these units?
-
Converting helps translate legacy or regional non-SI thermal conductivity data into units better suited for detailed analysis, facilitating comparison across different engineering standards.
