- Steradian - Math is Fun
A steradian is used to measure "solid angles" A steradian is related to the surface area of a sphere in the same way a radian is related to the circumference of a circle: The name steradian is made up from the Greek stereos for "solid" and radian So a full sphere has a surface area of 4π steradians which is about 12 57 steradians
- Steradian | Angle, Solid Angle, Radian | Britannica
Steradian, unit of solid-angle measure in the International System of Units (SI), defined as the solid angle of a sphere subtended by a portion of the surface whose area is equal to the square of the sphere’s radius
- Steradian - Explanation, Properties, Example, and FAQs
The steradian or square radian is the SI unit of solid angular measure The symbol used to represent steradian is ‘sr’ It is used to measure two-dimensional angular span in three-dimensional space, similar to the radian which quantifies planar angles

Geometry Trigonometry Spherical Trigonometry Steradian The unit of solid angle The solid angle corresponding to all of space being subtended is steradians
- Steradian Explained
A steradian can be defined as the solid angle subtended at the centre of a unit sphere by a unit area (of any shape) on its surface For a general sphere of radius, any portion of its surface with area subtends one steradian at its centre
- What Is Steradian Formula? - TimesMojo
A steradian is defined as the solid angle which, having its vertex at the center of the sphere, cuts off an area equal to the square of its radius The number of steradians in a beam is equal to the projected area divided by the square of the distance
