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 This Tool

Enter an angle value in the input field.
Select your source angle unit (Degrees, Radians, etc.).
View the converted angles and trigonometric functions.

Why Use This Tool

Convert CSS `rotate(45deg)` to JavaScript Canvas `ctx.rotate(radians)`.
Work with 3D game engines (WebGL, Three.js, Unity) which require radian inputs.

Pro Tips

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.
