1 radian=1.33 steradian

There is no direct ratio between radians and steradians since they measure different things. Radians measure angles in a two-dimensional plane, while steradians measure solid angles in three-dimensional space. However, both units are related by the formula: 1 steradian = (4π/1) square radians.

Is there any relatoin between radian and steradian?
nopes. radian is the ratio between the length of an arc and its radius. A steradian can be defined as the solid angle subtended at the center of a unit sphere by a unit area on its surface. For a general sphere of radius r, any portion of its surface with area A = r2 subtends one steradian.
How do you convert steradians into radian?
You do not convert. STERADIAN is a two dimensioal measurement RADIAN is a one dimensional measurement. Just as you cannot convert area into degrees (of angular measurement)
Is there any classification for supplementary units?
The supplementary units are the radian and steradian units. This SI classification was made in 1995 but was later abandoned and the units were regrouped as derived units.
How many radians are in one steradian?
None. A radian is a measure of angular separation in 1-dimensional space, a steradian is a measure in 2-dimensional space. It makes no sense to try to convert from one to the other.
What is the relationship between radian steradian degree?
if alpha is the solid angle subtended by a cone and theta is the 2d projection angle of this solid angle...Then----(both alpha and theta are in radians then) cos(theta) = 1 - (alpha/2*pi)
Is angle is a derived quantity?
From the Wikipedia article about the radian: "The unit was formerly a SI supplementary unit, but this category was abolished in 1995 and the radian is now considered a SI derived unit." The radian can be derived as the ratio between two lengths. That makes it a dimensionless unit.
What is scientific name of candle?
Candela is the current SI unit of luminous intensity, which is equal to 1/683 Watts per steradian with a frequency of 540 THz (lime colour as a specific fequency corresponds to a specific colour of light). A watt is 1 joule of energy per second, a steradian is the 3D equivalent of a radian.
What is 7900 radian in meters?
The only radian I know is the ratio of arc length to radius of the arc and as such has no units. It is used to measure angles and a full turn is 2π radians. So converting 7900 radian to meters is nonsense - unless there is another use of radian which I do not know.
What is the relation between radian and real numbers?
A radian is simply a measurement unit. The relation between a radian and real numbers is similar to the relation between a degree and real numbers or a metre and real numbers.
How many electrical charges are there in a radian?
There is no relationship between electric charge and a radian which is an angular measurement.
How many degrees in a solid angle?
The SI unit for measuring solid angles is a steradian : the stereo version of the 2-dimensional unit, the radian. The maximum value of a 3-d angle is 4*pi steradians which is approx equal to 41253 degrees.
Why the word or unit radian can be omitted when an angle is measured in radian?
As the ratio of two lengths, the radian is a "pure number" that needs no unit symbol, and in mathematical writing the symbol "rad" is almost always omitted. In the absence of any symbol radians are assumed, and when degrees are meant the symbol ° is used.
