Angle Conversion Formulas
Degrees to Radians
Radians = Degrees × (π/180)
Degrees to Gradians
Gradians = Degrees × (10/9)
Radians to Degrees
Degrees = Radians × (180/π)
Gradians to Degrees
Degrees = Gradians × (9/10)
These formulas are used by the calculator to perform accurate conversions between different angle units. The calculator uses π (pi) with a precision of 15 decimal places for maximum accuracy.

Frequently Asked Questions
What is the difference between degrees and radians?
Degrees and radians are two different units for measuring angles. A full circle is 360 degrees or 2π radians. Radians are the standard unit in many scientific and mathematical contexts, while degrees are more commonly used in everyday applications.
How do I convert degrees to radians?
To convert degrees to radians, multiply the degree value by π/180. For example, 90 degrees is equal to 90 × (π/180) = π/2 radians. Our calculator performs this conversion automatically.
What are gradians used for?
Gradians are used in some European countries and in older scientific literature. A full circle is 400 gradians, making the conversion between degrees and gradians straightforward. The calculator can convert between all three common angle units.
Is this calculator accurate for scientific work?
Yes, this calculator uses precise mathematical formulas and π with 15 decimal places for maximum accuracy. The formulas are clearly displayed on the page for verification.
