About International table calorie per second per square centimetre

The international table calorie per second per square centimetre (cal(IT)/(s·cm²)) equals exactly 41868 W/m² (1 cal(IT) = 4.1868 J; 1 cm² = 10⁻⁴ m²). The IT variant of the high-flux CGS unit, slightly larger than the thermochemical counterpart due to the IT calorie definition. 1 cal(IT)/(s·cm²) = 41868 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.
