The steradian is a unit of solid-angle measure in the International System of Units (SI). It is defined as the solid angle of a sphere subtended by a portion of the surface whose area is equal to the square of
So a full sphere has a surface area of 4π steradians which is about 12.57 steradians. That means one steradian covers roughly 8% of the sphere.And because we are measuring angles, it doesn't matter what size the sphere is it will always measure 4π steradians.Example: The "unit ...

Steradian isa unit of measurement for the solid angles. Steradian is the angle subtended, at the center of a sphere, by a surface whose magnitude of area is equal to square of the radius of the sphere. The solid angle of a sphere at it's centre is 4. steradians. ...
The steradian is the solid angle of a cone which, having its vertex in the centre of a sphere, cuts off on the surface of the sphere an area equal to that of a square with sides of length equal to the radius of the sphere Steradian je prostorski kot stožca z vrhom v središ...
A solid angle was defined asa ratio of an area to the square of a length. ... Since 1995 the unit of plane angle is defined as the dimensionless number “one”, equal to the ratio of a meter to a meter, and the unit of solid angle is also dimensionless number “one”, equal to...
