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 hour per square foot
The international table BTU per hour per square foot (BTU(IT)/(h·ft²)) equals 1055.05585262/(3600×0.09290304) ≈ 3.15459 W/m². The standard US heat flux unit in ASHRAE, ASTM, and building codes for thermal resistance (R-value), boiler ratings, and heat exchanger design. 1 BTU(IT)/(h·ft²) ≈ 3.15459 W/m².
