How to convert degrees to radians
To convert degrees to radians, multiply a degrees value by π/180.
Formula rad = ° × π/180
Example: Convert 90 degrees to radians Calculations: 90 ° × π/180 ≈ 1.571 rad
Degree (°)
The degree is a unit of angle, defined as 1/360 of a full circle. One degree is equal to π/180 radians, or 3600 arcseconds.
Radian (rad)
The radian is a unit of angle, defined as the angle subtended at the center of a circle by an arc whose length is equal to the radius of the circle. It is equal to 180/π degrees, or 648000/π arcseconds.
