About International table BTU per hour per square inch per degree Fahrenheit
The international table BTU per hour per square inch per degree Fahrenheit (BTU(IT)/(h·in²·°F)) equals ≈ 817.67 W/(m²·K) (1 in² = 6.4516×10⁻⁴ m²; 1 °F = 5/9 K). Encountered in US electronics thermal management, semiconductor package datasheets, and heat sink characterisation where contact areas are measured in square inches. 1 BTU(IT)/(h·in²·°F) ≈ 817.67 W/(m²·K).
About International table kilocalorie per hour per square metre per degree Celsius
The international table kilocalorie per hour per square metre per degree Celsius (kcal(IT)/(h·m²·°C)) equals 4186.8/3600 ≈ 1.1633 W/(m²·K) (1 kcal(IT) = 4186.8 J). The IT variant used in steam turbine, power plant, and process industry engineering. Numerically slightly larger than the thermochemical counterpart. 1 kcal(IT)/(h·m²·°C) ≈ 1.1633 W/(m²·K).
