About International table kilocalorie per hour per square centimetre

The international table kilocalorie per hour per square centimetre (kcal(IT)/(h·cm²)) equals 4186.8/(3600×10⁻⁴) = 11630 W/m² exactly (1 kcal(IT) = 4186.8 J; 1 h = 3600 s; 1 cm² = 10⁻⁴ m²). Used in IT-based thermodynamics for high heat flux surfaces such as boiler tubes. 1 kcal(IT)/(h·cm²) = 11630 W/m².

About Watt per square millimetre

The watt per square millimetre (W/mm²) equals exactly 10⁶ W/m². Used in high-power laser material processing - cutting, welding, and additive manufacturing - and electron beam applications. A 1 kW laser focused to 1 mm² achieves 1 W/mm². Numerically equal to MW/m². 1 W/mm² = 10⁶ W/m² = 100 W/cm².
