What is the Thermal Conductivity Calculator?

The Thermal Conductivity Calculator is a handy tool for physics students, engineers, and researchers to determine the thermal conductivity (kkk) of a material. Thermal conductivity measures a material’s ability to conduct heat and is a crucial property in heat transfer applications, building insulation, and material science. By entering the heat transfer, material thickness, cross-sectional area, temperature difference, and time, the calculator uses the formula: k=Q⋅LA⋅ΔT⋅tk = \frac{Q \cdot L}{A \cdot \Delta T \cdot t}k=A⋅ΔT⋅tQ⋅L​
to compute the material’s thermal conductivity in W/m\cdotpK\text{W/m·K}W/m\cdotpK.

How to Use:

1. Enter Heat Transfer (Q) in Joules: Input the amount of heat transferred through the material.
2. Enter Material Thickness (L) in meters: Input the thickness of the material layer through which heat is conducted.
3. Enter Cross-sectional Area (A) in m²: Input the surface area perpendicular to the heat flow.
4. Enter Temperature Difference (ΔT) in °C: Input the difference in temperature between the two sides of the material.
5. Enter Time (t) in seconds: Input the duration over which heat is transferred.
6. Click “Calculate”: The calculator determines the thermal conductivity using the given inputs.
7. Review Result: The output shows all entered values and highlights the calculated thermal conductivity in W/m\cdotpK\text{W/m·K}W/m\cdotpK for easy reference.
