Convert Thermochemical calorie per centimetre per second per degree Celsius to Kilowatt per metre kelvin

Convert Thermochemical calorie per centimetre per second per degree Celsius (cal(th)/(cm·s·°C)) to Kilowatt per metre kelvin (kW/(m·K)) instantly and accurately.

Thermochemical calorie per centimetre per second per degree Celsius (cal(th)/(cm·s·°C))
Kilowatt per metre kelvin (kW/(m·K))

Conversion Formula

kW/(m·K) = cal(th)/(cm·s·°C) × 0.4184

About Thermochemical calorie per centimetre per second per degree Celsius

The cal(th)/(cm·s·°C) equals exactly 4.184/0.01 = 418.4 W/(m·K) (1 thermochemical calorie = 4.184 J). The CGS thermal conductivity unit dominant in US physics and chemistry before SI adoption. Copper: ≈0.921; aluminium: ≈0.489 cal(th)/(cm·s·°C). Not equal to cal(IT)/(cm·s·°C). 1 cal(th)/(cm·s·°C) = 418.4 W/(m·K).

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).
