What are the units of solid angle in other systems ( In SI, it is steradian)
I wasn't aware that there were other 'assigned' units for the Solid Angle, I guess I should google more often! Thanks Halls!HallsofIvy said:The first thing I did was use good old "Google" which sent me to Wikipedia:
http://en.wikipedia.org/wiki/Solid_angle
where I learned that the corresponding units are "square degree" and "fractional area" (what fraction of a circle does it subtend?).
A solid angle is a measure of the amount of space covered by a three-dimensional shape when viewed from a specific point. It is measured in steradians (sr) and represents the portion of a sphere that is enclosed by the shape.
The SI unit for solid angle is the steradian (sr). One steradian is equal to the solid angle subtended by a surface at the center of a sphere with an area of one square meter.
In the metric system, the unit for solid angle is also the steradian (sr). This is consistent with the SI unit.
In the Imperial system, the unit for solid angle is the square degree (deg2). One square degree is equal to the solid angle subtended by a surface at the center of a sphere with an area of one square degree.
To convert between units of solid angle, you can use the following conversion factors:
Alternatively, you can use online unit converters or conversion formulas specific to the unit you are trying to convert to.
