Thermal Resistance Calculator

Calculate conductive thermal resistance based on material and geometry.

Input Parameters

mm

Material thickness in heat flow direction

cm²

Area perpendicular to heat flow

Results

Thermal Resistance
0.0098°C/W
Material Conductivity
205 W/(m·K)

Formula Used

Rth = L / (k × A)

Where L is thickness, k is thermal conductivity, and A is cross-sectional area.
