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. 


Langley

The langley (Ly) is a unit of radiant energy per unit area, equal to one thermochemical calorie per square centimetre (41,840 J/m²). Named after Samuel Pierpont Langley, it was widely used in meteorology and solar radiation research throughout the 20th century to express insolation values.
