Degrees vs Radians Calculator
Introduction & Importance
Understanding the difference between degrees and radians is crucial in mathematics, physics, and engineering. This calculator helps you convert between these units with ease.
How to Use This Calculator
- Enter a value in the ‘Value’ field.
- Select the unit (degrees or radians) from the ‘Unit’ dropdown.
- Click ‘Calculate’.
Formula & Methodology
The conversion formula from degrees to radians is radians = degrees * π / 180, and from radians to degrees is degrees = radians * 180 / π.
Real-World Examples
Example 1: Angle of a Triangle
A triangle has one angle of 90 degrees. What is this angle in radians?
Radians = Degrees * π / 180 = 90 * π / 180 = π / 2
Example 2: Circle Circumference
The circumference of a circle is 2πr. If the circumference is 6.28, what is the radius in degrees?
Degrees = Radians * 180 / π = 6.28 * 180 / π = 114.59 degrees
