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 Thermochemical kilocalorie per hour per square metre
The thermochemical kilocalorie per hour per square metre (kcal(th)/(h·m²)) equals 4184/3600 ≈ 1.1622 W/m² (1 kcal(th) = 4184 J; 1 h = 3600 s). Used in older continental European and Soviet-era building physics standards for wall and roof heat loss calculations. 1 kcal(th)/(h·m²) ≈ 1.1622 W/m².
