Radians to Degrees Converter

What is a Radian?

A radian (rad) is a unit of angular measure used in mathematics and engineering. It represents the angle created when the arc length equals the radius of a circle. 1 full circle = 2π radians (approximately 6.28318 radians).

Radians are widely used in trigonometry, calculus, and physics to express angles in formulas, making mathematical computations easier.

What is a Degree?

A degree (°) is a more familiar unit of measuring angles. 1 full circle = 360 degrees.

Degrees are commonly used in geometry, navigation, and everyday measurements where angles are represented in an easy-to-understand format.

How to Use the Radians to Degrees Converter?

• Enter Radians: In the "Enter Radians" field, input the value of the angle in radians that you wish to convert.
• Click 'Calculate': After entering the radians, click the Calculate button to perform the conversion.
• View Degrees Result: The resulting angle in degrees will be displayed in the "Degrees result" section once you click the Calculate button.
• View Angle Visualization: Below the result, you will see an Angle View section, where a visual representation of the angle is shown, making it easier to understand the degree measurement.
• Clear the Inputs: If you want to reset the inputs, click the Clear button. This will remove any data in both the radians input field and the degrees result.
• Use the π (Pi) Button: If you prefer to enter radians in terms of π (Pi), click the π button to insert the value of Pi into the radians field for easier conversion.

Radians to Degrees Formula

To convert radians to degrees, use the simple formula:

Degrees=Radians×π180​

Example: If you have an angle of π/4 radians,

Degrees=(π/4)×π180​=45°

This means π/4 radians = 45 degrees.

Frequently Asked Questions (FAQs)

How do I convert radians to degrees manually?

Use the formula: Degrees = Radians × (180 / π).

What is π radians in degrees?

π radians = 180 degrees.

How do I convert degrees to radians?

Use the formula: Radians = Degrees × (π / 180). You can also use this tool to convert deg to rad easily.

What is 1 radian in degrees?

1 radian ≈ 57.2958 degrees.

Is this a free radians to degrees calculator?

Yes! This free online radian to degree calculator instantly converts between radians and degrees with precision.

How to convert radians to degrees?

To convert radians to degrees, multiply the radian value by 180 and divide by π. This lets you express any angle in the more familiar degree system.

Is 1 radian 180 degrees?

No. One radian is approximately 57.3 degrees. In contrast, 180 degrees is equal to π radians.

What is 2π in degrees?

2π radians represent a full circle, which is equal to 360 degrees. This is a common way to describe a complete rotation.

How many radians is 45?

To convert degrees to radians, multiply the degree value by π and divide by 180. So, 45 degrees × π⁄180 = π⁄4 radians.
