What is an Angle Converter?
An angle converter is an essential tool for anyone working with geometry, trigonometry, physics, or engineering. It allows you to seamlessly translate angle measurements from one unit to another. Whether you're dealing with degrees for everyday use, radians for advanced mathematics, gradians for surveying, or DMS (Degrees Minutes Seconds) for precise navigation and astronomy, our online angle converter handles it all with high accuracy.
Our interactive tool is designed for ease of use, providing instant conversions directly in your browser. Unlike complex software, there’s no installation required – just input your value, select your units, and get your result. This tool is perfect for students, educators, engineers, surveyors, and anyone who needs quick and reliable angle conversions.
Understanding Angle Units
Different fields and applications use various units to measure angles. Here’s a brief overview of the units our converter supports:
Degree (°)
The most common unit, where a full circle is 360°. Used in everyday geometry and engineering.
Radian (rad)
A unit based on the radius of a circle, where a full circle is $2\pi$ radians. Fundamental in calculus and physics.
Gradian (grad)
Also known as "gon", where a full circle is 400 grad. Often used in surveying and some European countries.
DMS (Degrees Minutes Seconds)
A system where a degree is divided into 60 minutes, and each minute into 60 seconds. Used for precise navigation, latitude, and longitude.

How to Use the Angle Converter
Converting angles is straightforward with our tool. Follow these simple steps:
1. Enter Your Value
Input the numerical value of the angle you want to convert into the "Enter Angle Value" field. If converting from DMS, use the dedicated Degrees, Minutes, and Seconds input fields.
2. Select "From Unit"
Choose the unit of the angle you entered from the "From Unit" dropdown menu (e.g., Degree, Radian, Gradian, or DMS).
3. Select "To Unit"
Choose the unit you wish to convert your angle into from the "To Unit" dropdown menu.
4. View Converted Result
The conversion will happen automatically, and the result will be displayed in the "Result" box.
Common Angle Conversion Formulas
Here are the underlying formulas used in angle conversions, illustrating the relationships between different units:
- Degrees to Radians: $Radians = Degrees \times (\frac{\pi}{180})$
- Radians to Degrees: $Degrees = Radians \times (\frac{180}{\pi})$
- Degrees to Gradians: $Gradians = Degrees \times (\frac{10}{9})$
- Gradians to Degrees: $Degrees = Gradians \times (\frac{9}{10})$
- DMS to Decimal Degrees: $Decimal Degrees = Degrees + (\frac{Minutes}{60}) + (\frac{Seconds}{3600})$
- Decimal Degrees to DMS:
- Degrees = Integer part of Decimal Degrees
- Minutes = Integer part of $((Decimal Degrees - Degrees) \times 60)$
- Seconds = $(( (Decimal Degrees - Degrees) \times 60) - Minutes) \times 60$
Our converter handles these calculations automatically, so you don't have to!
Frequently Asked Questions (FAQ)
DMS stands for Degrees, Minutes, Seconds. It's a way of expressing angles (or geographic coordinates like latitude and longitude) using a sexagesimal (base-60) system, where 1 degree = 60 minutes and 1 minute = 60 seconds.
Yes, our angle converter supports both positive and negative angle values for all unit conversions.
Absolutely! Our online angle converter is completely free to use, with no hidden costs or subscriptions.
No, this is a web-based tool. You can access and use our angle converter directly from your browser on any device.
Degrees divide a circle into 360 parts, while radians relate the angle to the arc length of a circle's radius. A full circle is 360 degrees or $2\pi$ radians.
Gradians (or gons) are primarily used in surveying and some engineering fields, particularly in countries that adopted the metric system, as a right angle is exactly 100 gradians, simplifying calculations.
