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.

About Centesimal Seconds

A centesimal second (c″) is 1/10,000 of a gradian - exactly π/2,000,000 rad ≈ 1.5708 × 10⁻⁶ rad. In the gradian hierarchy, 1 right angle = 100 grad = 10,000 c′ = 1,000,000 c″. High-precision total stations calibrated in gons report to 0.1-1 c″, equivalent to ~0.0324 arcseconds. Used in French, Dutch, Swiss, and Scandinavian cadastral surveys. DIN 1313 designates 10 c″ = 1 milligon (mgon). 1 c″ ≈ 0.324″ sexagesimal = π/2,000,000 rad.
