Convert point to second (astronomy)
Selected category: angle.
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 second (astronomy):
Second (" or s or sec) is also a unit of angle measurement used in astronomy to count longitude. Astronomers divide the equator into 24 hours instead of 360 degrees and measure the right ascension, which is the longitude coordinate for positions in the sky, in units of time. This makes 1 second of longitude equal to 15 arcseconds.
