📐 Angle Converter - Degrees, Radians, Gradians
Convert between degrees, radians, and all angle units
📌 Key formulas
- 360° = 2π rad = 400 gon = 1 turn
- 1 rad ≈ 57.2958°
- 1° = 60 arcminutes = 3600 arcseconds
Angle Converter: Degrees, Radians, and Gradians
The Angle Converter lets you switch a single angle between the units used across mathematics, engineering, and design. Enter a value in one unit and the tool instantly shows the equivalent in the others, removing the need to remember conversion factors or work them out by hand.
It supports the units you meet most often. The degree divides a full circle into 360 parts and is the everyday unit for geometry and navigation. The radian is the natural unit of mathematics, where a full circle equals two pi radians, which makes it essential for calculus and trigonometry. The gradian, also called the gon, splits a circle into 400 parts and is used in some surveying work. You can also express an angle as a fraction of a full turn.
Who Uses Angle Conversions
Students moving between degree based and radian based formulas rely on quick conversions to keep their calculations consistent. Engineers, programmers, surveyors, and CAD users frequently switch units because software and reference tables do not always agree on a single convention. By giving you accurate results in every common unit at once, this converter helps you avoid the small mistakes that creep in when converting manually, especially around the pi based relationship between degrees and radians.
