Frequently Asked Questions
What are the different angle units?
Degrees (°): The most common unit, where a full circle is 360°. Radians (rad): Used in mathematics and physics, where a full circle is 2π rad. Gradians (grad): Where a full circle is 400 grad (less commonly used). Minutes ('): 1/60 of a degree. Seconds ("): 1/60 of a minute. Revolutions (rev): Complete turns, where 1 rev = 360°.
How precise are the conversions?
Our converter uses high-precision mathematical calculations and displays results with up to 10 decimal places. For most practical applications, 2-4 decimal places are sufficient. You can round the result as needed for your specific use case.
Can I convert negative angles?
Yes! Negative angles are valid in mathematics and represent clockwise rotation (while positive angles represent counterclockwise rotation). Simply enter a negative number in the input field, and the tool will convert it correctly.
What is the conversion formula between degrees and radians?
To convert from degrees to radians: radians = degrees × π / 180. To convert from radians to degrees: degrees = radians × 180 / π. Our tool handles all these formulas automatically, so you don't need to memorize them!
Is this tool free to use?
Absolutely! Our Angle Converter is completely free to use, with no registration required. We believe in providing high-quality, accessible tools for students, engineers, and anyone who needs to perform angle conversions quickly and accurately.
