About International table BTU per hour per square inch
The international table BTU per hour per square inch (BTU(IT)/(h·in²)) equals 1055.05585262/(3600×6.4516×10⁻⁴) ≈ 454.26 W/m². Used for high heat flux applications such as electronic component cooling, jet engine combustor walls, and nuclear fuel assembly design in US customary units. 1 BTU(IT)/(h·in²) ≈ 454.26 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.
