Definition and details for point:
Point (pt) is also a unit of angle measurement, used in navigation and it is equal to 1/32 of a circle, or 11° 15′, or pi/16 radians. On a compass, each right angle is divided in 8 points and each point can be subdivided in 4 quarter points. So 1 turn equals to 128 quarter-points. This is a binary navigation system of units (turn,point,quarter-point).
Definition and details for nanoradian:
Nanoradian (nrad) is a unit of angle measurement equal to 10-9 radian, or about 0.209 milliarcsecond (mas). Such tiny angles are used from astronomers and geologists.
