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)
