Thanks I see it now @kuruman ! Is the reason why they used radians instead of degrees in the arc length formula is because radians is a ratio of the length while degrees is not.

Many thanks!

Yes, both are dimensionless in the usual dimensionality system; they just have different units.

That said, many have found this unsatisfactory and have attempted to develop a dimension for angles. If interested, see https://www.physicsforums.com/insights/can-angles-assigned-dimension/
