Solid Angles in Steradian
Calculators and formula for calculating the solid angles in steradian
With this calculator the solid angle can be calculated as part of a spherical surface. The three-dimensional solid angle is the ratio of the area cut out (calotte) to the square of the radius of a cone cut out of a sphere.
The unit of measurement for the solid angle in the International System of Units is the steradian (unit symbol sr).
