About Degrees to Radians Conversion

Definition: A radian is the angle subtended by an arc equal in length to the radius of the circle.

Conversion Formula: radians = degrees × (π/180)

Key Relationships:

  • • 180° = π radians
  • • 360° = 2π radians (full circle)
  • • 90° = π/2 radians (quarter circle)
  • • 1° = π/180 ≈ 0.017453 radians
  • • 1 radian ≈ 57.2958 degrees

Common Angle Conversions:

30° = π/6
45° = π/4
60° = π/3
90° = π/2
120° = 2π/3
135° = 3π/4
150° = 5π/6
180° = π

Why Use Radians?

  • • Simplifies many mathematical formulas
  • • Natural unit for calculus and advanced mathematics
  • • Arc length = radius × angle (in radians)
  • • Derivatives and integrals of trig functions work cleanly
