What Is Angle Converter?
Angle Converter is a free online tool that converts between different units of angular measurement. Convert degrees, radians, gradians, and more with instant precision.
Key Features
Convert between all standard angle units. Real-time conversion as you type. High-precision results using double-precision math. Support for arcminutes and arcseconds. Clean interface showing all units.
Benefits
Essential for trigonometry, physics, and engineering calculations. Quickly switch between degree and radian systems. Accurate conversions for navigation and surveying.
Use Cases
Convert angles for trigonometric calculations in programming. Surveying and mapping coordinate conversions. Navigation bearing conversions. Physics and engineering angular measurements.
Tips for Best Results
Remember key conversions: 360 degrees = 2pi radians = 400 gradians. A right angle is 90 degrees, pi/2 radians, or 100 gradians. Most programming languages use radians for trig functions.
Frequently Asked Questions
Convert between degrees, radians, gradians, arcminutes, arcseconds, turns, and milliradians. All common angular measurement units are included.
Enter the angle in degrees and the radian equivalent appears instantly. The conversion factor is pi/180, so 180 degrees equals pi radians.
Gradians divide a circle into 400 units instead of 360 degrees. They are used in some surveying and engineering applications. A right angle is 100 gradians.
Yes. Angle conversions use exact mathematical formulas. Pi is calculated to full double-precision floating-point accuracy.
Milliradians are used in military, ballistics, and optics. One milliradian subtends approximately one meter at a distance of one kilometer.
