Angle Converter

Easily convert between Degrees (°) and Radians (rad). Essential for students, architects, engineers, and anyone working with geometry, trigonometry, or navigation.

Why Use It?

• Perfect for math, physics, astronomy, and engineering applications.
• Converts quickly and with high precision.
• Supports the most commonly used angle units.

Popular Conversions

• Degrees to Radians
• Radians to Degrees

Supported Units

• Degrees (°) - The most familiar unit of angle measurement; 360 degrees make a full circle.
• Radians (rad) - The SI unit for angles, based on the radius of a circle; 2π radians equal 360 degrees.

Common Uses

• Calculating angles in geometry and trigonometry problems.
• Converting navigation bearings.
• Performing calculations in physics and engineering involving rotational motion.
• Programming and computer graphics, where radians are often required.
• Astronomy and satellite trajectory computations.

Frequently Asked Questions

How many radians are in one degree?

One degree equals π/180 radians (approximately 0.01745 radians).

Why use radians instead of degrees?

Radians provide a natural measure of angles in mathematics and physics because they relate the angle directly to the radius and arc length of a circle.

Can I convert back and forth easily?

Yes. Degrees to radians: multiply by π/180. Radians to degrees: multiply by 180/π.

Are there other units for measuring angles?

Yes, such as gradians (or grads) and turns, but degrees and radians are by far the most common.
