Convert Watt per millimetre kelvin to International table calorie per centimetre per second per degree Celsius
Convert Watt per millimetre kelvin (W/(mm·K)) to International table calorie per centimetre per second per degree Celsius (cal(IT)/(cm·s·°C)) instantly and accurately.
Conversion Formula
cal(IT)/(cm·s·°C) = W/(mm·K) × 2.388458966
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 International table calorie per centimetre per second per degree Celsius
The cal(IT)/(cm·s·°C) equals exactly 4.1868/0.01 = 418.68 W/(m·K) (1 international table calorie = 4.1868 J). Used in pre-SI thermodynamics, steam tables, and international heat transfer references. Copper: ≈0.920 cal(IT)/(cm·s·°C). Slightly larger than cal(th)/(cm·s·°C). 1 cal(IT)/(cm·s·°C) = 418.68 W/(m·K).
