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.
About Milliwatt per square centimetre
The milliwatt per square centimetre (mW/cm²) equals exactly 10 W/m² (1 mW = 10⁻³ W; 1 cm² = 10⁻⁴ m²). Widely used in photonics, laser safety standards (IEC 60825), and UV dosimetry. Solar irradiance at Earth's surface ≈ 100 mW/cm². 1 mW/cm² = 10 W/m² = 0.001 W/cm².
