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.
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.
