Thermal Conductivity Calculator
Calculate thermal conductivity, heat transfer rates, and thermal resistance for various materials. Understand how different materials affect heat flow in engineering and construction applications.
Step 1: Material & Dimensions
Understanding Thermal Conductivity
Thermal conductivity (k) measures a material’s ability to conduct heat. Higher values indicate better heat conductors (metals), while lower values indicate better insulators (wood, air).
Step 2: Temperature & Calculation
Heat Transfer Formula
Heat flux (q) = (k × A × ΔT) / d, where k = thermal conductivity, A = area, ΔT = temperature difference, and d = thickness. Thermal resistance R = d / (k × A).

Heat Flow Analysis
Heat Transfer Formulas
Heat Flux (q) = k × A × ΔT / d | Thermal Resistance (R) = d / (k × A)
Heat flux represents the rate of heat transfer per unit area. Thermal resistance quantifies how strongly a material opposes heat flow. These calculations are essential for insulation design, heat exchanger sizing, and thermal management in engineering applications.
