About Arcsecond and Arcminute
The arcsecond is 1/3600 of a degree, or 1/60 of an arcminute. Telescope resolution, star parallax (the basis of the parsec), and GPS precision use arcseconds. The arcminute is 1/60 of a degree. Astronomy quotes apparent sizes (the full Moon spans about 31 arcminutes) and optometry rates visual acuity in arcminutes. One Arcsecond equals 0.01666666667 Arcminutes (1 arcsec = 0.01666666667 arcmin). Arcsecond is used in telescope resolution and in stellar parallax measurement. Arcminute is used in astronomy apparent sizes.
Precision and Rounding:Angle conversions are exact ratios of a full turn, but radian values involve π and never terminate in decimal form. Navigation and construction round to whole degrees or minutes; surveying, astronomy, and robotics carry six or more significant figures.
Conversion factors per NIST Special Publication 811 and the BIPM SI Brochure (9th edition) (reference).
