Firstly, One radian = 180/PI degrees and one degree = PI/180 radians. Therefore, for converting a specific number of degrees in radians, multiply the number of degrees by PI/180 (for example, 90 degrees = 90 x PI/180 radians = PI/2). To convert a specific number of radians into degrees, multiply the number of radians by 180/PI.

The radiance can also be spectrally resolved, i.e., decomposed into contributions from different wavelengths or optical frequencies; the total radiance can be written asExplanation. If a light source emits one candela of luminous intensity uniformly across a solid angle of one steradian, the total luminous flux emitted into that angle is one lumen (1 cd·1 sr = 1 lm). Alternatively, an isotropic one-candela light-source emits a total luminous flux of exactly 4π lumens. If the source were partly covered by an ideal absorbing hemisphere, that system would ...

abbreviation for steradian. Understanding the steradian is key to planning for the energy available in the application. To understand the steradian, we will first consider the radian.
