About Arcseconds

An arcsecond (″) is 1/3,600 of a degree - π/648,000 rad ≈ 4.848 × 10⁻⁶ rad. It is the fundamental resolution unit of classical astronomy and geodetic surveying. The Hubble Space Telescope delivers ~0.05″ resolution; atmospheric seeing at excellent sites gives 0.4-0.6″. Stellar parallax of Proxima Centauri is 0.7687″, defining its distance of 1.3009 parsecs. The parsec is defined as the distance at which 1 AU subtends exactly 1 arcsecond - giving 1 pc = 3.0857 × 10¹⁶ m. 1″ = π/648,000 rad ≈ 4.848 µrad.

About Warsaw Pact Mils

The Warsaw Pact mil equals 1/6,000 of a full circle - π/3,000 rad ≈ 1.0472 mrad. The Soviet military adopted this system, dividing the circle into 6,000 parts instead of the NATO standard 6,400. A full circle = 6,000 WP mils; a right angle = 1,500 mils. Used by Russia, Ukraine, Belarus, Finland, and other post-Soviet states. The 6.7% difference between WP and NATO mils (6,000 vs 6,400 per circle) can cause targeting errors of >1.5 m at 1,000 m if confused. 1 WP mil ≈ 1.0472 mrad = π/3,000 rad.
