About International table kilocalorie per hour per square centimetre
The international table kilocalorie per hour per square centimetre (kcal(IT)/(h·cm²)) equals 4186.8/(3600×10⁻⁴) = 11630 W/m² exactly (1 kcal(IT) = 4186.8 J; 1 h = 3600 s; 1 cm² = 10⁻⁴ m²). Used in IT-based thermodynamics for high heat flux surfaces such as boiler tubes. 1 kcal(IT)/(h·cm²) = 11630 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.
