About Watt per square metre
The watt per square metre (W/m²) is the SI coherent unit for heat flux density and irradiance. Solar irradiance at Earth's surface ≈ 1000 W/m²; solar constant ≈ 1361 W/m²; human skin radiative emission ≈ 100 W/m²; global average geothermal flux ≈ 0.087 W/m². Referenced in ISO 80000-4. 1 W/m² = 1 J/(s·m²) = 10⁻³ kW/m².
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.
