About Calorie per Second-Square Centimeter (cal/(s·cm²))
A CGS heat-flux unit equal to exactly 41,840 W/m² = 41.84 kW/m². Traditionally used in atmospheric physics, geophysics, and solar-radiation research, where the closely-related unit 'langley per minute' (1 langley = 1 cal/cm², so 1 ly/min = 1 cal/(min·cm²) = 696.7 W/m²) appears in historical solar-radiation observations published by US Weather Bureau, NOAA Surface Radiation Budget Network (SURFRAD), and the Smithsonian Astrophysical Observatory's pre-satellite solar-constant measurements. Used heavily in pre-1990s solar-energy literature, atmospheric-science textbooks (Iqbal 'An Introduction to Solar Radiation'), and geophysical heat-flow measurements at hydrothermal-vent fields. Reference values: peak summer-noon insolation in cal/(s·cm²) ≈ 0.024 (= ~1,000 W/m²); average global insolation ~0.006 cal/(s·cm²). Today mostly superseded by W/m² in publications and instrumentation, retained only for historical-record continuity.
About Watt per Square Meter (W/m²)
The SI unit of heat flux density (ISO 80000-5 §5-10) — the rate of heat-energy flow per unit area perpendicular to the flow direction. W/m² is the universal working unit in heat-transfer analysis (Fourier conduction q = −k·∇T, Newton's law of cooling q = h·ΔT, Stefan-Boltzmann radiation q = ε·σ·T⁴), solar-energy and atmospheric science, building-envelope thermal modeling, electronics cooling, and radiation intensity. Reference values: the solar constant at Earth's top of atmosphere is exactly 1,361 W/m² (the standard reference value defined by IAU 2015 Resolution B3 / SORCE TIM instrument data); a clear-sky noon at sea level ~1,000 W/m² (the standard test condition for photovoltaic module rating per IEC 61215); average daily Earth-surface insolation 150-250 W/m² (region-dependent); human body emits ~75-100 W/m² as black-body IR radiation at skin temperature; CMB cosmic microwave background ~3.13 × 10⁻⁶ W/m² at 2.725 K. Building-envelope U-factors (W/(m²·K)) multiplied by ΔT yield heat flux in W/m². Also the SI unit for irradiance, sound intensity (in acoustics), and Poynting-vector electromagnetic flux.
