## Definition of Degrees and Radians

Before delving into the conversion, let’s define what degrees and radians are. Degrees are a common unit of measuring angles, with a full circle being 360°. Radians, on the other hand, measure angles using the radius of a circle. A complete circle is represented by 2π radians.

Understanding the relationship between degrees and radians is crucial for effective conversion. One complete revolution around a circle, measured in degrees, is equal to 360° or 2π radians. This fundamental connection forms the basis for converting between these two angular units.

The formula for converting degrees to radians is straightforward:

Here, π (pi) is a mathematical constant approximately equal to 3.14. This formula allows us to convert any angle measured in degrees to its equivalent in radians.

## Conversion Steps

Let’s break down the conversion process into simple steps:

Step 1: Write down the numerical value of the angle given in degrees.

Step 2: Multiply the numerical value from Step 1 by π/180.

Step 3: Simplify the expression by canceling any common factors.

Step 4: The result obtained after simplification is the angle measure in radians.

For quick reference, here’s a chart showcasing some common angles in both degrees and radians:

## Conclusion

Converting degrees to radians is a fundamental skill in mathematics. By following the steps outlined in this guide, you can confidently perform this conversion for various angles. Remember to practice with different examples to reinforce your understanding. As you delve further into mathematical concepts, the ability to convert between degrees and radians will prove invaluable.

## FAQ

### How do we convert degrees to radians?

To convert the value of the angle in degrees to its equivalent radians, multiply the given value by π/180. For instance, the value of 180 degrees is equivalent to π radians.

### What is the formula to convert radians into degrees?

The formula to convert the value of an angle from radians to degrees is to multiply the given value by 180/π. For example, the value of 2π is equal to 360 degrees.

### How to convert 30 degrees to radians?

Multiply 30 degrees by π/180: (30 \times (\frac{\pi}{180}) = \frac{\pi}{6}). Hence, 30 degrees is equal to (\frac{\pi}{6}) in radians.

### What is the value of 1 radian?

One radian is approximately equal to 57.2958 degrees or 57 degrees, 17 minutes, and 44 seconds.

### How is pi radians equal to 180 degrees?

One complete counterclockwise revolution in an XY plane is equal to 2π radians or 360 degrees. Thus, we can express it as an equation: (2\pi = 360^\circ) or (\pi = 180^\circ). Therefore, pi is equal to 180 degrees.
