Joule/Square Meter

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. 


Btu (IT)/Square Foot

The British thermal unit (IT) per square foot (Btu/ft²) is an imperial unit of heat density used in North American building energy analysis, fire protection engineering, and solar radiation assessment. One Btu/ft² equals approximately 11,356 J/m².
