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 Erg per second per square centimetre
The erg per second per square centimetre (erg/(s·cm²)) equals exactly 10⁻³ W/m² in SI (1 erg = 10⁻⁷ J; 1 cm² = 10⁻⁴ m²). The CGS irradiance unit used in classical electromagnetic theory, astrophysics, and older radiation physics literature. Numerically equal to the milliwatt per square metre. 1 erg/(s·cm²) = 10⁻³ W/m² = 1 mW/m².
