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.
