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.
Arcminute (′)
An arcminute (′ or MOA) is 1/60 of a degree. Arcminutes measure astronomical object sizes (Moon: ~31 arcminutes), visual acuity (normal vision resolves 1 arcminute), and rifle scope adjustments (1 MOA ≈ 1 inch at 100 yards). GPS coordinates use degrees and arcminutes.
