Angle Converter — Degree, Radian, Gradian, Arcminute & Arcsecond

Easiest Converter’s angle converter gives fast, precise conversions for math, CAD, navigation, surveying, astronomy, and graphics work. Convert between degree (°), radian (rad), gradian (gon), arcminute (′), and arcsecond (″) with clean, copy-ready output.

The tool references radians internally for consistent trigonometry across applications. Popular pairs include deg ⇄ rad for calculators and code, deg ⇄ gon for surveying, and deg ⇄ arcmin/arcsec for optical and celestial measurements.

Why this angle converter? Inputs are keyboard-friendly, there’s a one-tap swap, and the result line is easy to copy for notes or CAD comments. Values use sensible precision so numbers stay readable without losing accuracy.

Supported units: degree (°), radian (rad), gradian (gon), arcminute (′), arcsecond (″). Whether you’re coding, drafting, or charting a course, the converter keeps angle math quick and consistent.
