About International table kilocalorie per hour per square metre
The international table kilocalorie per hour per square metre (kcal(IT)/(h·m²)) equals 4186.8/3600 ≈ 1.1633 W/m² (1 kcal(IT) = 4186.8 J; 1 h = 3600 s). The IT variant used in steam engineering, solar thermal collector standards, and process heat calculations. 1 kcal(IT)/(h·m²) ≈ 1.1633 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.
