Convert Kilowatt per square metre to Thermochemical kilocalorie per hour per square metre
Convert Kilowatt per square metre (kW/m²) to Thermochemical kilocalorie per hour per square metre (kcal(th)/(h·m²)) instantly and accurately.
Conversion Formula
kcal(th)/(h·m²) = kW/m² × 860.4206501
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.
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.
