About Megawatt per square metre

The megawatt per square metre (MW/m²) equals exactly 10⁶ W/m². Used in fusion reactor engineering (plasma-facing components: 10-20 MW/m²), concentrated solar power tower receivers (≈1-3 MW/m²), and hypervelocity shock studies. Numerically equal to W/mm². 1 MW/m² = 10⁶ W/m² = 1 W/mm².

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.
