Angle Converter

Convert between degrees, radians, gradians and other angle units.

Angle Input

Value Unit Decimal places

Results

Enter a value to convert it across the angle units used in math, CAD, navigation, surveying, and astronomy.

Degrees Radians Turns Gradians / gon Arcminutes Arcseconds Milliradians Degrees, minutes, seconds

Reference

Full circle 360 deg = 2π rad = 1 turn = 400 gon

Right angle 90 deg = π/2 rad = 100 gon

Fine measurements 1 deg = 60 arcmin = 3,600 arcsec

Tool Introduction

Use this angle converter to switch between degrees, radians, turns, gradians, arcminutes, arcseconds, and milliradians. It is tuned for everyday engineering, trigonometry, mapping, CAD, and field measurement work.

Degrees are convenient for drawings and navigation, radians are standard in math and programming, and turns are useful when working with rotations. Arcminutes and arcseconds handle very small angles used in optics, astronomy, and geographic coordinates.
