Free Angle Converter - Convert Degrees, Radians, Gradians Online

A A gradian divides a full circle into 400 parts (a right angle = 100 grad). It is mainly used in surveying and some European countries.

A An arcminute is 1/60 of a degree, and an arcsecond is 1/60 of an arcminute (1/3600 of a degree). They are used in astronomy and navigation for precise measurements.

A Radians are standard in mathematics and physics (especially calculus and trigonometry). Degrees are more intuitive for everyday use, navigation, and geometry.

A A 'turn' represents one complete rotation, equivalent to 360 degrees, 2π radians, or 400 gradians. It's a fundamental unit often used in mathematics, engineering, and sports to describe full rotations or revolutions. Degrees, on the other hand, subdivide a turn into 360 equal parts, offering finer granularity for angle measurements in navigation, geometry, and everyday contexts. Our online angle converter helps you instantly convert between these and many other angle units.

A While this online angle converter doesn't accept Degree-Minute-Second (DMS) format directly, you can efficiently convert its individual components. Simply convert your arcminutes and arcseconds to their decimal degree equivalents using the tool, then add them to your whole degree value. This method allows you to process precise angle measurements for navigation, surveying, or astronomy tasks, leveraging our support for degrees, arcminutes, and arcseconds.

A Our free online angle converter provides the simplest and most accurate method. Instead of remembering complex formulas for degrees, radians, gradians, arcminutes, or turns, you can input your value into one unit field and instantly see its equivalent in all other supported angle units. This saves time, reduces calculation errors, and ensures precision for engineering, astronomy, or any project requiring exact angle conversions.

A Online angle converters, like ours, typically use highly precise algorithms for calculations, often achieving the same or even greater accuracy than standard scientific calculators. Our free tool leverages robust mathematical libraries to ensure conversions between degrees, radians, gradians, arcminutes, arcseconds, and turns are performed with high fidelity, reducing human error. This makes it a reliable choice for academic, engineering, and navigational tasks requiring exact angle values.

A Absolutely. You can input decimal values for any supported unit, including degrees. For example, typing `45.5` into the degrees field will instantly show you its equivalent in radians, gradians, and other units. This feature is super handy for anyone working with precise measurements in fields like engineering or woodworking.

A Yes, negative angles work fine here. Enter -90 degrees and you'll get -1.5708 radians or -100 gradians. This is useful for representing clockwise rotations or directional changes in physics and engineering. Just type your negative number directly into any unit field.

A Close, but not exact. One radian equals 180/π degrees, roughly 57.2957795. That 57.3 figure is a rounded shortcut, fine for quick mental math but not for precision work. Our converter uses the full π value internally, so you'll get accurate results down to many decimal places. Try converting 1 radian in the tool and you'll see the exact decimal.
