About This Tool

The Angle & Trigonometry Unit Converter converts angles across 6 geometric units (Degrees, Radians, Gradians, Arcminutes, Arcseconds, and Revolutions/Turns) while simultaneously calculating primary trigonometric ratios (sin, cos, tan).

Key Features

Converts between Degrees (°), Radians (rad), Gradians (grad), Arcminutes (′), Arcseconds (″), and Turns (rev)

Computes exact π-multiples for Radians (e.g. π/2, π/4, 2π)

Live trigonometric sine, cosine, and tangent evaluation

Unit circle quadrant position detection

How to Use

Why Use ToolSnippet Angle & Trigonometry Unit Converter?

Convert CSS `rotate(45deg)` to JavaScript Canvas `ctx.rotate(radians)`.

Work with 3D game engines (WebGL, Three.js, Unity) which require radian inputs.

Tips for Best Results

To convert Degrees to Radians, multiply by π / 180.
To convert Radians to Degrees, multiply by 180 / π.

Frequently Asked Questions

How many radians are in a full circle?

A full 360-degree circle equals exactly 2π radians (~6.283185 rad).

What is a Gradian?

A Gradian (gon) is a metric unit of angle where a right angle is defined as exactly 100 gradians, making a full circle 400 gradians.
