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 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.
