Convert Thermochemical kilocalorie per hour per square metre to Kilowatt per square metre
Convert Thermochemical kilocalorie per hour per square metre (kcal(th)/(h·m²)) to Kilowatt per square metre (kW/m²) instantly and accurately.
Conversion Formula
kW/m² = kcal(th)/(h·m²) × 0.001162222222
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 Kilowatt per square metre
The kilowatt per square metre (kW/m²) equals exactly 1000 W/m². Standard for concentrated solar collectors (parabolic trough ≈ 20-80 kW/m² at focus), industrial infrared heaters, and induction heating surfaces. 1 kW/m² = 1000 W/m² = 0.1 W/cm² = 100 mW/cm².
