About the Turn (turn)
The Turn is one full rotation, equal to 360 degrees — used in fields like robotics and audio (turntable speed) where counting full revolutions is more intuitive than degrees.

The Radian is the SI unit of angle, defined so a full circle equals 2π radians — the natural unit for calculus and most programming math functions (Math.sin, Math.cos, etc.).
