About Watt per metre kelvin

The watt per metre kelvin (W/(m·K)) is the SI unit for thermal conductivity defined by Fourier's law q = -λ∇T. Materials span orders of magnitude: aerogels ≈0.015, glass ≈1.0, stainless steel ≈16, aluminium ≈205, copper ≈385, diamond ≈2200 W/(m·K). Referenced in ISO 22007, EN 12667, and all major international standards. 1 W/(m·K) = 1 W/(m·°C).

About Kilowatt per metre kelvin

The kilowatt per metre kelvin (kW/(m·K)) equals exactly 1000 W/(m·K). Used for exceptionally conductive materials: type IIa diamond ≈2.2 kW/(m·K), isotopically pure ²⁸Si ≈1.0 kW/(m·K), single-crystal graphene > 5 kW/(m·K) at room temperature. Convenient for comparing advanced thermal management and heat spreader materials. 1 kW/(m·K) = 1000 W/(m·K).
