About These Units
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.
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.
