About Arcsecond

Definition: The arcsecond (symbol: ″) is one-sixtieth of an arcminute or 1/3600 of a degree, used for extremely precise angular measurements.

History: Finest traditional subdivision of angular measurement, critical for precision astronomy and geodetic surveying.

Current Use: Essential in astronomy, satellite positioning, precision surveying, and scientific applications requiring ultimate angular precision.

Examples: Astronomical measurements: star positions, satellite tracking: precise orbits, geodesy: Earth measurements, telescope resolution

About Turn

Definition: The turn (symbol: tr) represents one complete rotation or revolution, equal to 360 degrees or 2π radians.

History: Natural unit representing complete rotational motion, used in mechanical systems and rotational applications.

Current Use: Used for describing rotational speed, mechanical rotations, and complete angular motions in engineering.

Examples: Motor rotations: RPM (revolutions per minute), mechanical systems: gear ratios, astronomy: planetary rotations
