No. Degrees (and radians) are used only to measure 2-dimensional angles.
You can't measure spatial angles (I think that the mathematical term
is "solid angle") with degrees.
Solid angles are measured in steradians. The solid angle subtended by
a surface is defined as the surface area of a unit sphere covered by
the surface's projection onto the sphere.
The solid angle corresponding to all of space being subtended
is 4*pi steradians.
