Turns Are Better Than Radians

A recent article published on ComputerEnhance, titled “Turns are better than radians,” argues that the unit of a full rotation—known as a turn—offers practical advantages over the traditional radian measure for expressing angles. The piece, which has attracted modest attention on the Hacker News forum, received ten points and three comments from readers who engaged with its technical claims.

The author outlines several reasons for preferring turns: they map directly to fractions of a circle, eliminating the need for the 2π factor that appears in many trigonometric formulas; they are dimensionless like radians but provide an intuitive sense of proportion, making mental calculations and educational explanations more straightforward. The article cites examples from programming, physics, and engineering where using turns simplifies code and reduces errors, and it notes that some language libraries already support turn‑based constants. While a few commenters raised concerns about compatibility with established mathematical conventions, the overall discussion highlighted a growing interest in re‑examining angle‑measurement standards.
