Frequently Asked Questions

How accurate is this radians to degrees converter?

Our converter uses JavaScript’s built-in Math.PI constant (approximately 15 decimal places of precision) for calculations, providing mathematically exact results for all practical purposes.

Can I convert degrees back to radians with this tool?

Absolutely! The converter works both ways. You can enter values in degrees to get radians, or use the “Swap Units” button to quickly reverse the conversion direction.

When would I need to convert between radians and degrees?

Radians are commonly used in higher mathematics, physics, and computer graphics, while degrees are more familiar in everyday applications. Conversions are frequently needed in trigonometry, angular velocity calculations, and when working with different software tools.

How do I estimate radians to degrees without a calculator?

For rough estimates: 1 radian ≈ 57.3° (the exact conversion is 180/π ≈ 57.2958°). To convert radians to degrees, multiply by approximately 57. For degrees to radians, divide by 57. For precise conversions, use our tool.

What’s the relationship between π and angle conversion?

π radians equals 180 degrees, which is the fundamental relationship between these units. This means a full circle (360°) equals 2π radians, and a right angle (90°) equals π/2 radians.
