Convert Microwatt per metre kelvin to Watt per millimetre kelvin
Convert Microwatt per metre kelvin (µW/(m·K)) to Watt per millimetre kelvin (W/(mm·K)) instantly and accurately.
Conversion Formula
W/(mm·K) = µW/(m·K) × 1.000000000e-9
About Microwatt per metre kelvin
The microwatt per metre kelvin (µW/(m·K)) equals exactly 10⁻⁶ W/(m·K). Used for near-vacuum conditions and evacuated superinsulation systems where the effective thermal conductivity falls well below the mW/(m·K) range. Evacuated multi-layer insulation (MLI) at high vacuum can reach 0.001-10 µW/(m·K) effective conductivity. Completes the SI prefix chain below mW/(m·K). 1 µW/(m·K) = 10⁻⁶ W/(m·K) = 10⁻³ mW/(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).
