Popular Conversions
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.
