What are Watt/sq. and Apostilb

Definition of Watt/sq.

Watt per square centimeter per steradian, denoted as W/sq. Cm/sr, is a unit of measurement used in radiometry to quantify radiant intensity over a given area and solid angle. Specifically, it measures the power emitted from a unit area in a particular direction, expressed per steradian. This unit is particularly useful in understanding the distribution of radiant energy and is often employed in fields such as optics, physics, and engineering. By providing a standardized measure, it facilitates the comparison and analysis of radiant energy across different systems and applications.

Definition of Apostilb

An apostilb is a unit of luminance, representing the brightness perceived by the human eye. It is part of the metric system and is used to quantify the luminous intensity per unit area of light passing through or emitted from a surface. One apostilb equals one lumen per square meter per steradian. This unit is instrumental in fields like photometry and lighting design, helping to assess and compare the effectiveness of various lighting systems. By providing a clear measure of brightness, apostilbs aid in creating environments with optimal lighting conditions for human activities.
