Convert between degrees, radians, and gradians.
Convert between degrees, radians, and gradians
90° =0.00000000 rad
Formula: rad = deg × π/180
90° = π/2 rad = 100 grad
180° = π rad = 200 grad
270° = 3π/2 rad = 300 grad
360° = 2π rad = 400 grad
45° = π/4 rad = 50 grad
30° = π/6 rad ≈ 33.33 grad
60° = π/3 rad ≈ 66.67 grad
1 radian ≈ 57.3°
Degrees: A circle is divided into 360 degrees. Most commonly used in everyday applications.
Radians: The standard unit in mathematics and physics. One full rotation = 2π radians.
Gradians: A metric-based unit where a right angle is 100 gradians and a full circle is 400 gradians.
