Understand radian measure as arc length on the unit circle.

Convert a radian measure to degrees using the unit-circle relationship

Problem

What is \(\pi~\text{radians}\) in degrees?

Big Picture

What this problem is really about

Radian-to-degree conversion uses the same half-turn equivalence in the opposite orientation. Put degrees in the numerator and radians below so the radian unit and any matching pi factor cancel cleanly. Interpreting the original angle as a fraction of a turn gives a fast reasonableness check.
