    When angles are measured in radians, they are simply the ratio of arclength divided by radius ... as taught in high school geometry, at least in the USA.

    An important note to make is that regardless of the units you're using to measure an angle, its dimensions are still the same, none. :) The only difference is a conversion factor.
