Conversion Formula
BTU(IT)/(s·ft²) = kW/m² × 0.08805509184
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 International table BTU per second per square foot
The international table BTU per second per square foot (BTU(IT)/(s·ft²)) equals 1055.05585262/0.09290304 ≈ 11357 W/m² (= 3600 × BTU(IT)/(h·ft²)). Used for extreme heat flux: atmospheric re-entry aerodynamic heating, solid rocket nozzle throat, and nuclear reactor thermal hydraulics design. 1 BTU(IT)/(s·ft²) ≈ 11357 W/m².
