Frequently Asked Questions
What is the relationship between degrees and radians?
A full circle is 360 degrees or 2π radians. Therefore, 180 degrees = π radians. To convert degrees to radians, multiply by π/180. To convert radians to degrees, multiply by 180/π.
Why are radians used in higher mathematics?
Radians provide a more natural approach to angles when working with trigonometric functions, calculus, and physics. They simplify many mathematical formulas, particularly those involving derivatives and integrals of trigonometric functions.
How precise are the conversions?
Our tool provides conversions accurate to 10 decimal places. For most practical purposes, 4-6 decimal places are sufficient. You can see more precise values by increasing the decimal places in the input.
Can I use this tool on my mobile device?
Absolutely! Our converter is fully responsive and works seamlessly on smartphones, tablets, and desktop computers. The touch-friendly interface makes it easy to use on any device.
Is there a limit to how many conversions I can do?
No, there are no usage limits. You can perform as many conversions as you need, completely free of charge. No registration or account is required.
