Thermal Resistance Calculator

Find thermal resistance, heat flow, or temperature difference.

CALCULATE

Formulas

R = L / (k × A)

L = thickness, k = thermal conductivity, A = area

ΔT = P × R

Temperature difference from power and thermal resistance

Thermal Resistance

Conductivities (W/m·K): Copper: 385, Aluminum: 237, Steel: 50, Glass: 1.0, Wood: 0.15, Air: 0.025. Critical for electronics cooling and building insulation.
