Conversion Formula

Formula

To convert an angle from radians to degrees, use the following formula:

Degrees = Radians × (180/π)

Where π (pi) is approximately 3.141592653589793.

This formula comes from the fact that a full circle is 360 degrees or 2π radians. Therefore, one radian is equal to 180/π degrees.

Example Calculation

Let's convert π/2 radians to degrees:

Start with the angle in radians: π/2
Multiply by 180/π: (π/2) × (180/π) = 90
The result is 90 degrees

This means π/2 radians is equivalent to 90 degrees, which is a right angle.

Did You Know?

The conversion factor 180/π (approximately 57.2958) is a fundamental constant in mathematics that relates radians to degrees.

Common Mistakes to Avoid

When converting polar coordinates to degrees, be careful about these common errors:

Forgetting to multiply by 180/π - this is the key conversion factor
Using the wrong value for π - always use the precise value or a calculator's π function
Mixing up radians and degrees in your calculations
Not simplifying the result to the simplest form when possible

Double-check your calculations, especially when dealing with complex angles or multiple conversions.

FAQ

What is the difference between radians and degrees?: Degrees and radians are both units for measuring angles. A full circle is 360 degrees or 2π radians. Radians are the natural unit of angular measurement in mathematics, while degrees are more commonly used in everyday contexts.
Why do I need to convert radians to degrees?: You might need to convert radians to degrees when working with different measurement systems, when interpreting trigonometric functions, or when presenting results to an audience that uses degrees.
Is the conversion from radians to degrees exact?: Yes, the conversion is exact when using the precise value of π. The formula Degrees = Radians × (180/π) will always give you the correct conversion.
Can I convert degrees to radians with this calculator?: No, this calculator specifically converts from radians to degrees. For the reverse conversion, you would use the formula Radians = Degrees × (π/180).
What if I enter an invalid value in the calculator?: The calculator will display an error message if you enter a non-numeric value. Make sure to enter a valid number for the angle in radians.
