What to enter
| Input | Meaning and units |
|---|---|
| Thickness (m) | Enter thickness in m; use the same basis as the other measurements. |
| Conductivity (W/(m·K)) | Enter conductivity in W/(m·K); use the same basis as the other measurements. |
| Area (m²) | Area in square metres. Convert both dimensions consistently before multiplying them. |
Understanding your result
Read Thermal resistance (K/W) in the units and model stated on this page. The formula resistance=length/(k*area) defines the relationship; measurement accuracy and model applicability are separate from numerical precision.
Common mistakes
- Mixing input units or changing the physical meaning of a variable without changing the model.
Check your calculation
- Use the worked example as a known reference case, then change one input at a time and check the direction and units of the response.
