Convert Kilowatt per metre kelvin to Watt per millimetre kelvin
Convert Kilowatt per metre kelvin (kW/(m·K)) to Watt per millimetre kelvin (W/(mm·K)) instantly and accurately.
Conversion Formula
W/(mm·K) = kW/(m·K) × 1
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).
About Watt per millimetre kelvin
The watt per millimetre kelvin (W/(mm·K)) equals exactly 1000 W/(m·K) since 1 mm = 10⁻³ m. Used in microelectronics thermal engineering where components are millimetre-scale: copper ≈0.385, silicon ≈0.148 W/(mm·K). Thermal interface material datasheets for high-performance pads and solder joints commonly use this unit. 1 W/(mm·K) = 1000 W/(m·K) = 10 W/(cm·K).
