About Quadrants

A quadrant equals 1/4 of a full circle - π/2 rad = 90°, the right angle. Perpendicularity underpins Euclidean geometry, the Pythagorean theorem, and Cartesian coordinate systems. In AC electrical engineering, voltage and current in purely reactive circuits are exactly 90° out of phase, defining reactive power in VAr. The four quadrants of the unit circle determine the sign of sine, cosine, and tangent. GPS orbital elements encode latitude in semicircles bounded by ±1 quadrant = ±90°. 1 quadrant = 90° = 100 grad = π/2 rad = 1,600 NATO mils.

About Compass Points

A compass point equals 1/32 of a full circle - π/16 rad ≈ 0.19635 rad (= 11.25°). Traditional maritime compasses divide the horizon into 32 named points from North clockwise back to North, each further divided into quarter-points (2.8125°). This 32-point rose was the standard for European seafaring from the 14th to 19th centuries. Modern navigation uses three-digit decimal bearings (000°-359°), but compass roses persist in meteorology and nautical heritage. 1 compass point = 11.25° = 11°15′ = 200 NATO mils.
