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 Arcminute (1 arcsec = 0.01666666667 arcmin). Arcsecond to Arcminute conversion comes up most often in telescope resolution and in stellar parallax measurement, typically when figures need restating for 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).

Worked Example

15 Arcsecond equals 0.25 Arcminute.

15 arcsec × 0.01666666667 = 0.25 arcmin
