Angle Converter

Loading tool...

Angles are a fundamental concept in geometry, physics, and engineering, but the units used to measure them can vary depending on the field. Whether you're a student working on trigonometry, an engineer designing complex parts, or an astronomer tracking celestial bodies, our Angle Converter is designed to help you switch between degrees, radians, and turns with mathematical precision.

Understanding the relationship between different angular units is crucial for accurate calculations. Degrees are the most common unit in everyday life, while radians are the standard in advanced mathematics because of their relationship to a circle's radius. Meanwhile, gradians are used in surveying, and 'turns' or revolutions are often seen in mechanical engineering. Our tool removes the need for manual conversion formulas, providing instant results that you can count on.

We believe that technical utilities should be fast and simple. Our Angle Converter works directly in your browser on any device. There's no account to create and no software to download. Just enter your angle, choose your units, and see the conversion immediately. It’s a reliable companion for anyone who needs to handle angular data quickly and accurately.

How to Convert Angles Step-by-Step

  1. 1

    Enter the angle value you want to convert in the 'From' field.

Angular Unit Basics

What is a Radian?

A radian is the standard unit of angular measure used in mathematics. One full circle is equal to 2π radians (approx. 6.283).

Degrees vs. Gradians

A full circle is 360 degrees. In the gradian system (mostly used in surveying), a full circle is divided into 400 gradians.

Frequently Asked Questions

Which angle units are supported?

We support Degrees (°), Radians (rad), Gradians (grad), Turns (rev), Minutes of arc ('), and Seconds of arc (").

How accurate is the angle conversion?

Our tool uses high-precision constants, including Pi, to ensure your angular measurements are as accurate as possible for all calculations.

How many degrees are in Pi radians?

Pi (π) radians is exactly equal to 180 degrees.

What is a 'turn' in angle measurement?

A 'turn' (also called a revolution or rotation) is equal to one full circle, or 360 degrees.

Is the Angle Converter free to use?

Yes, it is 100% free with no limits on usage.

Does it work on mobile devices?

Yes, our tool is fully optimized for smartphones, tablets, and desktop browsers.

What are arcminutes and arcseconds?

These are smaller units of angular measure. 1 degree is divided into 60 arcminutes, and each arcminute is divided into 60 arcseconds.

Is my data private?

Yes. All processing happens locally in your own browser. No values are sent to our servers.

Why use radians instead of degrees?

Radians are often preferred in calculus and advanced physics because they simplify many mathematical formulas involving circles and oscillation.

How do I swap units quickly?

Click the swap button located between the two unit dropdowns to instantly reverse your conversion direction.
