About Watt per square inch
The watt per square inch (W/in²) equals 1/(6.4516×10⁻⁴) ≈ 1550.003 W/m² (1 in = 0.0254 m). Used in US electronics thermal management for PCB power density, semiconductor die heat flux, and power module ratings. 1 W/in² ≈ 1550 W/m² ≈ 0.155 W/cm².
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.
