What is the unit of solid angle?
A steradian.
How many degrees are there in one steradian?
65.54
How many degrees are in one pi steradian?
None. A degree 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.
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.
What are the metric units?
The International System of Units (generally referred to as the "SI") is the system of units of measurement, based on the metric system adopted in France in 1791. The SI base units are:Length: metre/meter (m)Mass: kilogram (kg)Time: second (s)Electric current: ampere (A)Temperature: kelvin (K)Luminous intensity: candela (CD)Amount of substance: mole (mol)All other units are derived from those seven. They include:Frequency: hertz (Hz)Angle: radian (rad)Force: newton (N)Pressure: pascal (Pa)Energy: joule (J)Power: watt (W)Electric potential: volt (V)Electric charge: coulomb (C)Capacitance: farad (F)Inductance: Henry (H)Resistance: ohm (Ω)Magnetic flux: weber (Wb)Magnetic field strength: tesla (T)Electric conductance: siemens (S)Solid angle: steradian (sr)Temperature: Celsius (°C)Luminous flux: lumen (lm)Illuminance: lux (lx)Radioactivity: becquerel (Bq)Adsorbed dose of ionizing radiation: gray (Gy)Equivalent dose of ionizing radiation: sievert (SV)Catalytic activity: katal (kat)

Is there any relatoin between radian and steradian?
Yes, there is a relationship between radian and steradian as they both measure angles in three-dimensional space. One steradian is equivalent to a solid angle that subtends a surface area on a sphere that is equal to the square of the sphere's radius. This relationship allows for connections between angular measurements in two and three dimensions.
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.
How many degrees are in one steradian?
None. A degree 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.
How many degrees are in one pi steradian?
None. A degree 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 ratio between radian and 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 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 bright is 15000000 candlepower in lumens?
Cannot be converted as the dimensions of the units do not match. You can however convert candlepower to lumen/steradian.
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.
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)
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)
