steradian
In the International System of Units, the derived unit of solid angle; the solid angle subtended at the centre of a sphere of radius r by a portion of the surface of the sphere that has area r2. Symbol: sr
A steradian is defined as the solid (spatial) angle which, having its vertex at the center of the sphere, cuts off an area equal to the square of its radius So, 1 steradian has a projected area of 1 square meter at a distance of 1 meter, etc A sphere contains 4*pi steradians
A unit solid angle on the surface of a sphere equal to the square of the sphere's radius
A unit of solid angle One steradian equals the solid angle subtended at the center of a sphere by 0 25PI of the surface area of a sphere of unit radius
Steradian is the solid angle that, having its vertex in the center of a sphere, cuts off an area of the surface of the sphere equal to that of a square with sides of length equal to the radius of the sphere
the unit of solid angle adopted under the Systeme International d'Unites
In the International System of Units, the derived unit of solid angle; the solid angle subtended at the centre of a sphere of radius r by a portion of the surface of the sphere that has area r[2]. Symbol: sr
A solid angle with vertex at the center of a sphere of radius r that encompasses an area of r2 on the surface of the sphere
  The metric unit of solid angle   See metric system
The common unit used to measure solid angle, equal to a unit area cut in the surface of the unit sphere Since the surface area of the unit sphere is 4pi, the maximum solid angle is 4pi steradians
