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, …So the area is 4 pi r^2. A radian is the angle of radius r rolled on a circle. A steradian is the solid angle of area r^2 rolled onto a sphere.

How much "field of view" is covered by a surface or object from a point. Solid angle is measured in steradians (much like angles are measured in radians). The solid angle covering all directions (i.e. a full "field of view") is 4π steradians. Its symbol is Ω See: Steradian SteradianFormula of Radian. 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.Radiant intensity [Luminous intensity] watts per steradian [candelas] W/sr [cd] watts per steradia' square meter W/sr"m2 Radiance [Luminance] [candelas per square meter] [cd/m2] Table 1-2: Comparisons of radiant units with photometric units (shown in brackets [ ]) Steradian Technologies is a biotech startup developing the RUMI, the first noninvasive, fully-portable infectious disease diagnostic that costs the price of ...This is a directional quantity, measured as Watts per steradian per square meter (W/sr·m 2) Radiance is sometimes referred to casually as "intensity" (just as luminance is commonly referred to as "brightness.").
