Mouse Sensitivity Converter & ADS FOV Calculator

How this calculator works

This mouse sensitivity converter helps you carry the same aiming “feel” from one game to another. Different shooters use different input scales, so a sensitivity setting of 2.0 in one title can feel wildly different in another. The calculator bridges that gap by translating your current setup into an equivalent sensitivity for a new game, so your muscle memory stays consistent.

The key concept is cm/360, the physical distance your mouse travels to turn your character a full 360 degrees. This measurement is hardware‑agnostic and makes it easy to compare across games. To get cm/360, the tool uses your DPI (dots per inch), in‑game sensitivity, and the game’s yaw coefficient (the value that maps mouse input to degrees turned). Once cm/360 is calculated for your current game, the same distance is applied to your target game to produce a matching sensitivity. We also show eDPI (DPI × sensitivity) as a quick reference, though cm/360 is the more reliable cross‑game anchor.

Scoped and ADS aim is calculated separately with focal-length scaling. Enter your hipfire FOV and monitor aspect ratio, then choose the scope zoom that matches your optic. The ADS table gives both the focal scale multiplier and the full scoped sensitivity value, so you can copy whichever format your game exposes.

Some games label sensitivity differently. Fortnite is handled as a percent-style number, so enter 8 for 8%. Rainbow Six Siege is handled as the 1-100 hipfire slider with the standard multiplier setup. Decimal-based games such as Rust should be entered exactly as the in-game value appears.

Step-by-step

1. Select your current game and the game you want to convert to.
2. Enter your mouse DPI and your current in‑game sensitivity.
3. Enter your hipfire FOV, FOV type, aspect ratio, and custom scope zoom if needed.
4. Read the hipfire conversion and the scoped sensitivity table.
5. Apply the result in game, then test in a practice range to fine‑tune.

This is useful anytime you switch titles or update settings. For example, if you move from a tactical shooter to a battle royale, you can keep your preferred aim speed without hours of relearning. It’s also helpful when you change hardware—like moving from 800 DPI to 1600 DPI—because you can quickly re‑compute the sensitivity that preserves your feel. Streamers and competitive players often use this approach to keep their aim stable across scrims, tournaments, or new releases.

Focal-length scaling preserves screen-space movement near the crosshair, which is why it is useful for low-zoom ADS and scoped rifles. Different games may still apply their own scope curves, rounding, or per-weapon settings, so treat the calculated value as the mathematically matched baseline before personal preference. The calculator runs entirely in your browser, so you can load it once and use it offline at events or LANs without sharing any data.

Setup tips for consistent aim

• Lock in a DPI (e.g., 800 or 1600) and only adjust sensitivity per game to minimize hardware variables.
• Record your cm/360 and eDPI somewhere easy to reach so you can restore settings after driver updates.
• Match field of view when possible—different FOVs change perceived speed even with identical cm/360.
• Use the focal scale as your ADS multiplier when the game exposes multipliers instead of per-scope sens values.
• Test conversions in a practice range, then fine-tune with small increments (0.02-0.05) until it feels right.
• Large mousepads help maintain lower sensitivities without running out of space during long flicks.
