Questions
How do I convert degrees to radians?
Multiply the degree value by π/180. For example, 90° = 90 × π/180 = π/2 ≈ 1.5708 radians.
What is a gradian?
A gradian (also called a gon) divides a right angle into 100 parts, so a full circle is 400 gradians. It is used in some surveying and engineering applications.
What is a turn in angle measurement?
One turn equals a full 360-degree rotation (2π radians). The turn unit is sometimes used in CSS animations and mathematical contexts where full rotations are more intuitive than degrees.
Which angle unit does CSS use?
CSS supports deg (degrees), rad (radians), grad (gradians), and turn units in properties like rotate and hue-rotate. Degrees are the most commonly used.
