http://qudt.org/schema/qudt/SolidAngleUnit
The solid angle subtended by a surface S is defined as the surface area of a unit sphere covered by the surface S's projection onto the sphere.
A solid angle is related to the surface of a sphere in the same way an ordinary angle is related to the circumference of a circle.
Since the total surface area of the unit sphere is 4*pi, the measure of solid angle will always be between 0 and 4*pi.
