Thermal Conductivity Calculator

Find the heat conduction rate through a material.

Thermal conductivity (W/(m·K))

Area

Temperature difference (K)

Thickness

Calculated Output

Heat transfer rate (W) 80

Formula: Q/t = k·A·ΔT ÷ d

Step-by-Step Breakdown

1. Values used:

2. Thermal conductivity = 0.04 W/(m·K)

3. Area = 10

4. Temperature difference = 20 K

5. Thickness = 0.1

7. Heat transfer rate = 80W

Did this calculator solve your problem today?

The math behind it

Q/t = k·A·ΔT ÷ d. Low-k materials (like insulation) slow heat flow.

Insulation (k 0.04), 10 m², ΔT 20 K, 0.1 m → 80 W.

What has high conductivity?

Metals like copper and aluminium; gases and foams are poor conductors.
