About Nanowatt per square metre
The nanowatt per square metre (nW/m²) equals 10⁻⁹ W/m². Used in astrophysics and cosmology for quantifying extremely weak radiation fields, such as cosmic microwave background intensity and residual thermal emission from near-absolute-zero objects. Relevant in precision cryogenic sensor calibration. 1 nW/m² = 10⁻⁹ W/m² = 10³ pW/m².
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.
