About Thermochemical kilocalorie per hour per square centimetre
The thermochemical kilocalorie per hour per square centimetre (kcal(th)/(h·cm²)) equals 4184/(3600×10⁻⁴) ≈ 11622 W/m² (= 10⁴ × kcal(th)/(h·m²)). A high-flux variant of the metric heat flux unit found in older combustion engineering and furnace design references. 1 kcal(th)/(h·cm²) ≈ 11622 W/m².
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.
