Why sensitivity matching matters
Rainbow Six rewards small corrections. A bad sensitivity change can break timing. It can also disturb recoil control. This calculator helps you keep the same mouse feel after a DPI change. It estimates cm per 360. That value is useful because it describes real mouse travel. It is easier to compare than a raw sensitivity number.
Better control for Siege aim
Many players change DPI when buying a new mouse. Others adjust sensitivity after changing desk space. A direct guess can feel close, but it is rarely exact. The tool uses eDPI and the game sensitivity multiplier. It then converts the setting for your new DPI. This keeps the turn distance close to the original setup.
Advanced inputs for practical testing
The calculator supports horizontal and vertical sensitivity. It also includes ADS value, scope factor, field of view, and target cm per 360. The target mode is useful when you already know your preferred turning distance. Enter that distance, choose your new DPI, and calculate a matching sensitivity. You can then test it in Terrorist Hunt, shooting range, or custom games.
How to read the result
The converted horizontal value is the main hip-fire result. The vertical value follows your current vertical ratio. The ADS estimate shows how scoped aim may feel compared with hip aim. Scope factor is only an estimate. Real perception can change with FOV, monitor distance, aspect ratio, and optic zoom. Use the values as a strong starting point.
Recommended workflow
Start with your current settings. Save the result as CSV or PDF. Apply the new sensitivity in the game. Warm up for ten minutes. Track recoil on a wall. Then make small changes. Avoid changing DPI, hip sensitivity, ADS, and FOV all at once. Change one item at a time. This makes testing cleaner. It also helps you understand what improved your aim.
Fine tuning notes
Small adjustments work best. Try changes of one or two sensitivity points. Keep your mouse pad position the same. Use the same operator and weapon during tests. Record misses, over flicks, and under flicks. A lower cm value turns faster. A higher cm value turns slower. Pick the option that supports stable crosshair placement.
