SUMMARY
The discussion clarifies that 1 steradian is equivalent to 1 radian squared, specifically in the context of solid angle measurement. This relationship arises from the three-dimensional nature of a sphere, where a steradian defines the solid angle that subtends an area of one square unit on the surface of a unit sphere. The analogy to radians, which measure angles in a two-dimensional circle, emphasizes the geometric connection between these two concepts.
