cm / 360° describes what your hand actually does.

It is the physical desk distance required to turn the game camera through one complete rotation. Unlike a game slider number, it can be compared across compatible games and DPI settings.

Smaller means faster

At 20 cm / 360°, twenty centimetres of mouse travel completes a full turn. At 40 cm / 360°, the same movement completes only half a turn. A lower distance therefore produces more camera rotation from the same hand movement.

Why slider numbers are not universal

A sensitivity value of “1” can mean something entirely different in two games. Each game defines how mouse counts become camera rotation, and some games use percentages or nonlinear scales. cm / 360° avoids the label and describes the physical outcome.

How to measure cleanly

  1. Use horizontal hip-fire aiming in a quiet practice area.
  2. Point at a fixed landmark and mark the front-centre tip of the mouse.
  3. Move in a straight line without lifting until the view turns exactly 180°.
  4. Measure that distance and double it for cm / 360°.
  5. Repeat. Two matching checks are stronger than one.
Use one reference point. Start and finish with the same front-centre tip of the mouse. Measuring from the side, centre or sensor changes the distance.

What it does not capture

Matching cm / 360° does not automatically match field of view, scoped sensitivity, monitor-distance feel or acceleration. Use it for horizontal hip-fire rotation, then verify the result inside each game.

Why the ruler is optional at first

The assessment can compare responses from raw mouse counts while your DPI remains unchanged. The physical reference is only needed to express the winning response in centimetres and carry it reliably across hardware settings.
