About Thermochemical calorie per second per square centimetre
The thermochemical calorie per second per square centimetre (cal(th)/(s·cm²)) equals exactly 41840 W/m² (1 cal(th) = 4.184 J; 1 cm² = 10⁻⁴ m²). The CGS unit for very high heat flux: ablation heat flux during atmospheric re-entry ≈ 1-100 cal/(s·cm²). Used in plasma physics and aerospace thermal protection. 1 cal(th)/(s·cm²) = 41840 W/m².
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.
