Convert International table calorie per second per square centimetre per degree Celsius to International table BTU per hour per square foot per degree Fahrenheit
Convert International table calorie per second per square centimetre per degree Celsius (cal(IT)/(s·cm²·°C)) to International table BTU per hour per square foot per degree Fahrenheit (BTU(IT)/(h·ft²·°F)) instantly and accurately.
Conversion Formula
BTU(IT)/(h·ft²·°F) = cal(IT)/(s·cm²·°C) × 7373.38117
About International table calorie per second per square centimetre per degree Celsius
The international table calorie per second per square centimetre per degree Celsius (cal(IT)/(s·cm²·°C)) equals exactly 41868 W/(m²·K) (1 cal(IT) = 4.1868 J; 1 cm² = 10⁻⁴ m²; 1 °C = 1 K). Slightly larger than the thermochemical variant; used in IT-based thermophysical property tables for extreme thermal environments such as nuclear and fusion reactor surfaces. 1 cal(IT)/(s·cm²·°C) = 41868 W/(m²·K).
About International table BTU per hour per square foot per degree Fahrenheit
The international table BTU per hour per square foot per degree Fahrenheit (BTU(IT)/(h·ft²·°F)) equals 1055.05585262/(3600×0.09290304×5/9) ≈ 5.6783 W/(m²·K). The dominant heat transfer coefficient unit in US engineering: ASHRAE handbooks, ASTM standards, boiler and heat exchanger design, and building envelope U-values are all commonly tabulated in this unit. 1 BTU(IT)/(h·ft²·°F) ≈ 5.6783 W/(m²·K).
