What is the unit for measuring angles that is defined so that a full circle contains 360 of these units?

Explanation:
The unit used so a full circle contains 360 of these units is the degree. This convention splits a circle into 360 equal parts, so a complete rotation is 360 degrees. It’s handy because common angles line up nicely: a right angle is 90 degrees and a straight angle is 180 degrees. Each degree can be divided into 60 minutes, and each minute into 60 seconds, so a full circle has 360 × 60 × 60 = 1,296,000 arcseconds. For comparison, angles can also be measured in radians, where a full circle is 2π radians, with 1 degree equal to π/180 radians.
