About Celsius Heat Unit per hour per square foot

The Celsius heat unit per hour per square foot (CHU/(h·ft²)) equals (9/5)×1055.05585262/(3600×0.09290304) ≈ 5.6783 W/m². The CHU (= 9/5 BTU(IT)) uses a 1 °C temperature interval instead of 1 °F; historically used in UK and Canadian heating engineering. 1 CHU/(h·ft²) ≈ 5.6783 W/m² = (9/5) × BTU(IT)/(h·ft²).

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.
