Convert Watt per millimetre kelvin to Milliwatt per metre degree Celsius
Convert Watt per millimetre kelvin (W/(mm·K)) to Milliwatt per metre degree Celsius (mW/(m·°C)) instantly and accurately.
Conversion Formula
mW/(m·°C) = W/(mm·K) × 1000000
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).
About Milliwatt per metre degree Celsius
The milliwatt per metre degree Celsius (mW/(m·°C)) equals exactly 1 mW/(m·K) = 10⁻³ W/(m·K) since temperature intervals 1 °C = 1 K. Used interchangeably with mW/(m·K) in building physics, insulation standards (EN ISO 10456), and material datasheets where Celsius is the preferred temperature scale. Still air ≈26 mW/(m·°C); mineral wool ≈35 mW/(m·°C). 1 mW/(m·°C) = 1 mW/(m·K) = 10⁻³ W/(m·K).
