The watt per steradian (W/sr) is a unit of power density in the International System of Units (SI). It is used to measure the intensity of radiation emitted by a point source in a particular direction. The unit is derived from the watt, the SI unit of power, and the steradian, the SI unit of solid angle. One watt is equal to one joule per second.Radians are a fundamental unit of measurement, as are metres, grams, seconds, ampere, kelvin, candela, steradian & mol. Metre is the fundamental unit for length; Gram is the fundamental unit for mass (kilograms in SI units) Second is the fundamental unit for time; Ampere is the fundamental unit for electrical currentA 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. So, 1 steradian has a projected area of 1 square meter at a distance of 1 meter. 1 cendala pada cahaya memiliki frekuensi 540 x 1012 Hz menggunakan intensitas radian di arah 1/628 watt per steradian.

Answer. Steradians are a measure of the angular 'area' subtended by a two dimensional surface about the origin in three dimensional space, just as a radian is a measure of the angle subtended by a one dimensional line about the origin in two dimensional (plane) space. Steradians are equivalently referred to as 'square radians.'.Add steradian as a unit of solid angle, making it dimensionally equivalent to radian -squared.
