The Angular Size Calculator allows you to calculate the angular size of an object based on its actual length and distance from the observer. It can also compute the object’s length or the viewing angle if the other parameters are known. Results can be expressed in degrees or radians, and input units include meters, centimeters, millimeters, feet, and inches.
