Convert International table calorie per centimetre per second per degree Celsius to Watt per metre degree Celsius

Convert International table calorie per centimetre per second per degree Celsius (cal(IT)/(cm·s·°C)) to Watt per metre degree Celsius (W/(m·°C)) instantly and accurately.

International table calorie per centimetre per second per degree Celsius (cal(IT)/(cm·s·°C))
Watt per metre degree Celsius (W/(m·°C))

Conversion Formula

W/(m·°C) = 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 degree Celsius

The watt per metre degree Celsius (W/(m·°C)) equals exactly 1 W/(m·K) since temperature intervals 1 °C = 1 K. Widely used in building physics (EN ISO 6946), HVAC engineering, and European material datasheets as an equivalent notation. Stone: ≈2.5 W/(m·°C); softwood timber: ≈0.14 W/(m·°C); glass wool: ≈0.04 W/(m·°C). 1 W/(m·°C) = 1 W/(m·K).
