Understanding Angle Units
Degrees (°)
A full circle is 360 degrees. This is the most common unit of angular measurement in everyday life.
Radians (rad)
A full circle is 2π radians. Radians are standard in higher mathematics and physics because they relate angle to arc length.
Gradians (grad)
A full circle is 400 gradians. Sometimes called gons, they are used primarily in surveying to divide a right angle into 100 parts.
