A solid angle, measured from a vertex, is the ratio between the area subtended by the angle at the vertex and the the square of the distance to the vertex. The unit of measurement is the stradian.

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.

it is same as surface and volume ! a plane angle is 2D and solid angle is 3D

It is a solid angle, or an angle in 3-d space.

Usually an angle is measured in degrees or radians.

Particle displacement is a measurement of distance of the movement of a particle in a medium as it transmits a wave. Distance is measured in meters.

That would be an angle; the SI unit for angle is the radian. However, that is not the unit that is commonly used in this case.
