Instantly convert angles between degrees, radians, and gradians with our free online calculator. Perfect for trigonometry, engineering, and physics, ensuring accuracy in all your angular measurements. Understand the relationships between these fundamental units.
Formula:
The core conversions are based on the following relationships:
- Degrees to Radians:
Radians = Degrees × (π / 180) - Radians to Degrees:
Degrees = Radians × (180 / π) - Degrees to Gradians:
Gradians = Degrees × (10 / 9) - Gradians to Degrees:
Degrees = Gradians × (9 / 10) - Radians to Gradians:
Gradians = Radians × (200 / π) - Gradians to Radians:
Radians = Gradians × (π / 200)
Where π (pi) ≈ 3.14159265359
