Converting between degrees and radians is fundamental in mathematics, navigation, surveying, and engineering. Degrees are most common in everyday use, radians in calculus and physics, and gradians in surveying.
20 deg = 0.349066 rad
20 (twenty) degree(s) is equal to 0.349066 (zero) radian(s)
What is degree?
The degree (°) is the most common angle unit, with 360 degrees in a full rotation. It is used in navigation, construction, geography, and everyday descriptions of turns and rotations.
What is radian?
The radian (rad) is the SI unit of angle. One radian is the angle subtended at the centre of a circle by an arc equal in length to the radius. A full circle equals 2π radians. It is essential in calculus and physics.
