Convert Watt per square inch to Thermochemical kilocalorie per hour per square centimetre
Convert Watt per square inch (W/in²) to Thermochemical kilocalorie per hour per square centimetre (kcal(th)/(h·cm²)) instantly and accurately.
Conversion Formula
kcal(th)/(h·cm²) = W/in² × 0.1333654675
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 centimetre
The thermochemical kilocalorie per hour per square centimetre (kcal(th)/(h·cm²)) equals 4184/(3600×10⁻⁴) ≈ 11622 W/m² (= 10⁴ × kcal(th)/(h·m²)). A high-flux variant of the metric heat flux unit found in older combustion engineering and furnace design references. 1 kcal(th)/(h·cm²) ≈ 11622 W/m².
