Convert Thermochemical kilocalorie per hour per square metre to International table calorie per second per square centimetre
Convert Thermochemical kilocalorie per hour per square metre (kcal(th)/(h·m²)) to International table calorie per second per square centimetre (cal(IT)/(s·cm²)) instantly and accurately.
Conversion Formula
cal(IT)/(s·cm²) = kcal(th)/(h·m²) × 2.775920087e-5
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.
About International table calorie per second per square centimetre
The international table calorie per second per square centimetre (cal(IT)/(s·cm²)) equals exactly 41868 W/m² (1 cal(IT) = 4.1868 J; 1 cm² = 10⁻⁴ m²). The IT variant of the high-flux CGS unit, slightly larger than the thermochemical counterpart due to the IT calorie definition. 1 cal(IT)/(s·cm²) = 41868 W/m².
