About International table kilocalorie per hour per square metre
The international table kilocalorie per hour per square metre (kcal(IT)/(h·m²)) equals 4186.8/3600 ≈ 1.1633 W/m² (1 kcal(IT) = 4186.8 J; 1 h = 3600 s). The IT variant used in steam engineering, solar thermal collector standards, and process heat calculations. 1 kcal(IT)/(h·m²) ≈ 1.1633 W/m².
About Thermochemical kilocalorie per hour per square metre
The thermochemical kilocalorie per hour per square metre (kcal(th)/(h·m²)) equals 4184/3600 ≈ 1.1622 W/m² (1 kcal(th) = 4184 J; 1 h = 3600 s). Used in older continental European and Soviet-era building physics standards for wall and roof heat loss calculations. 1 kcal(th)/(h·m²) ≈ 1.1622 W/m².
