Convert International table calorie per centimetre per second per degree Celsius to Watt per metre kelvin
Convert International table calorie per centimetre per second per degree Celsius (cal(IT)/(cm·s·°C)) to Watt per metre kelvin (W/(m·K)) instantly and accurately.
Conversion Formula
W/(m·K) = cal(IT)/(cm·s·°C) × 418.68
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).
About Watt per metre kelvin
The watt per metre kelvin (W/(m·K)) is the SI unit for thermal conductivity defined by Fourier's law q = -λ∇T. Materials span orders of magnitude: aerogels ≈0.015, glass ≈1.0, stainless steel ≈16, aluminium ≈205, copper ≈385, diamond ≈2200 W/(m·K). Referenced in ISO 22007, EN 12667, and all major international standards. 1 W/(m·K) = 1 W/(m·°C).
