About Calorie per Second-Square Centimeter (cal/(s·cm²))
A CGS heat-flux unit (1 cal/(s·cm²) = 41,840 W/m²). Traditionally used in atmospheric physics and geophysics — the related "langley per minute" appears in historical solar-radiation records and older climate-science literature. Today mostly superseded by W/m² in publications.
About BTU per Hour-Square Foot (BTU/(hr·ft²))
An imperial heat-flux unit used in US HVAC, building-envelope analysis, and heat-exchanger design. ASHRAE design loads, solar heat-gain tables for windows, and HVAC equipment ratings commonly use BTU/(hr·ft²). Common peak solar heat gain through a south-facing window might be 200–300 BTU/(hr·ft²). 1 BTU/(hr·ft²) ≈ 3.155 W/m².
