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.
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.
