Free Angle Converter – Degrees, Radians & Gradians

Enter a value in the radians field and the degrees result updates at once. The formula is degrees = radians × 180 / pi, so pi radians shows as 180 degrees. The converter handles it both ways.

A gradian, also called a gon, divides a full circle into 400 units instead of 360 degrees, so a right angle is 100 gradians. It is used mainly in surveying, and the converter supports it directly.

Kisi bhi unit ke box mein value type karo — jaise degrees, radians ya gradians — aur baaki units turant update ho jayengi. Trigonometry ke liye bahut useful hai. Sab browser mein hota hai.

90 degrees equals pi/2 radians, which is about 1.5708 radians. Enter 90 into the degrees field and the converter shows the exact radian value instantly.

Yes. After the page loads, the converter runs entirely in your browser using JavaScript, so it keeps working without an internet connection and never contacts a server.

Yes. The tool uses the exact pi-based relationships with full decimal precision, making it reliable for trigonometry, calculus, physics, and engineering work.

Yes. Besides degrees, radians, and gradians, the converter supports arcminutes and arcseconds, which are useful in astronomy, navigation, and precise angular measurement.

Yes. Everything is processed in your browser. No value you enter is uploaded, logged, or shared, so your data stays entirely on your own device.
