In the International System of Units (SI), a solid angle is expressed in a dimensionless unit called a steradian (symbol: sr). One steradian corresponds to one unit of area on the unit sphere surrounding the apex, so an object that blocks all rays from the apex would cover a number of steradians equal to the total surface area of the unit sphere, .is the steradian (sr), and the radiant intensity is measured in watts per steradian. When the sensitivity of a typical human eye is taken into account, the power is called luminous flux, expressed in lumens, and the luminous intensity is given in lumens per steradian, otherwise called candelas. The increasing

Radiance is a measure of radiant intensity per unit of projected source area in a specified direction. The term exitance is a measure of the amount of radiant fluxFormula 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.
