Joule/Square Metre

The joule per square metre (J/m²) is the SI unit of radiant exposure or heat density. It represents the total energy incident on or passing through a unit area. Used in solar radiation measurements, laser energy delivery, and thermal analysis to quantify energy flux integrated over time. 


Calorie (th)/Square Centimetre

The thermochemical calorie per square centimetre (cal(th)/cm²) equals 41840 J/m². It was used in older atmospheric and solar radiation measurements. It is closely related to the langley unit and is encountered in historical climatological and solar energy data.
