About These Units
Arcsecond (″)
An arcsecond (″) is 1/60 of an arcminute or 1/3600 of a degree. Arcseconds measure stellar positions, telescope resolution, and atmospheric seeing. The Hubble Space Telescope resolves about 0.05 arcseconds. GPS accuracy is measured in arcseconds.
Turn (turn)
A turn (revolution, cycle, or rotation) is one complete 360° rotation. Turns simplify rotational calculations: 0.5 turns = 180°, 0.25 turns = 90°. Used in engineering, dance choreography, and describing rotational motion. Also called "full rotation" or "cycle."
