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 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.
