In terms of the SI unit radians this is π/10800 or approximately 0.290 888 x 10-3 rad. Radians. Parsecs. So 1 arc second of a 1 foot diameter circle is equal to .000029 inches. We can use this as a reference, as it's the same size as the full moon (which we're all familiar with), so if Conversely the shorter the focal length the larger the number of arc seconds covering each pixel. 1 atm = 1.013 x 106 dyne/cm2 = 1.013 x 105 Pa = 14.7 lb/in2. Please enable Javascript to use p = parallax, measured in arcseconds The parsec is defined as the distance at which a star has a parallax of 1 arcsecond. Astronomers used trigonometry to calculate the distance to stars long before the term parsec was coined, but the new unit made it easier to conceptualise unfathomable distances. How many arc-seconds in 16 milliarc-seconds: If θ mas = 16 then θ arcsec = 0.001 × 16 = 0.016 arcsec.
