This free mouse DPI calculator converts your in-game sensitivity when you switch DPI so your mouse keeps the exact same feel. It uses the standard formula new sensitivity = current sensitivity × (current DPI ÷ new DPI), which keeps your eDPI and 360° turn distance identical — no need to relearn your aim. Pick from 100+ gamesto see your exact 360° turn distance and whether your eDPI lands in that game's competitive range, and enter sensitivity as a decimal or percentage.

Mouse DPI Conversion Guide

How DPI Conversion Works

When you raise your DPI, the game gets more sensor counts per inch, so the camera moves faster. To keep the same feel you lower your in-game sensitivity by the same factor. The formula is simple:

New sensitivity = Current sensitivity × (Current DPI ÷ New DPI)

Worked example: you play at 800 DPI with 1.0 sensitivity and want to move to 1600 DPI. New sensitivity = 1.0 × (800 ÷ 1600) = 0.5. Both setups equal 800 eDPI, so your aim feels exactly the same — you just doubled your sensor resolution.

What Is eDPI?

eDPI (effective DPI) is the single number that describes your true sensitivity:

eDPI = DPI × In-game sensitivity

Two players with the same eDPI move their crosshair the same amount for the same hand motion, even if one uses 400 DPI / 1.6 sens and the other 1600 DPI / 0.4 sens. That is why pros compare eDPI instead of raw DPI or sensitivity — and why a correct DPI conversion always keeps eDPI fixed.

Understanding cm/360 (Turn Distance)

cm/360is how far you physically slide the mouse to spin a full circle in-game. It is the most intuitive way to describe sensitivity because it maps directly to your mousepad. It depends on DPI, sensitivity, and each game's yaw constant (Source-engine games like CS2 use 0.022, Valorant uses 0.07):

cm/360 = (360 ÷ (yaw × sensitivity)) ÷ DPI × 2.54

Because converting DPI keeps eDPI constant, your cm/360 does not change — which is the proof that the new settings feel identical. The calculator shows your turn distance for the selected game so you can sanity-check the result.

When to Use This Calculator

  • New mouse: your old DPI step isn't available, so convert to one your new mouse supports.
  • Copying a pro: you want a pro's eDPI but at your own preferred DPI.
  • Fixing your DPI: you measured your real DPI with the Mouse DPI Analyzer and need to re-derive your sensitivity.
  • Experimenting: you want to try high DPI for smoother tracking without losing your aim.

Common DPI Conversion Mistakes

  • Changing only DPI and forgetting to lower sensitivity — your aim ends up wildly faster.
  • Leaving Windows pointer speed off the default (6th notch) and "Enhance pointer precision" on, which adds acceleration and skews the feel.
  • Chasing huge DPI numbers — past your sensor's native DPI you gain nothing and can add jitter.
  • Comparing raw sensitivity between players instead of eDPI or cm/360.

Frequently Asked Questions

A mouse DPI calculator converts your sensitivity when you change your mouse DPI so the mouse keeps the exact same feel. Enter your current DPI and in-game sensitivity plus the new DPI you want, and it returns the new sensitivity that keeps your effective sensitivity (eDPI) and 360° turn distance identical.
Multiply your current sensitivity by your current DPI, then divide by the new DPI: new sensitivity = current sensitivity × (current DPI ÷ new DPI). For example, going from 800 DPI at 1.0 sensitivity to 1600 DPI gives 1.0 × 800 ÷ 1600 = 0.5 sensitivity. Both setups share the same eDPI, so your aim feels the same.
eDPI (effective dots per inch) is your DPI multiplied by your in-game sensitivity — for example 800 DPI × 0.5 sensitivity = 400 eDPI. Because eDPI combines both values into one number, it is the fairest way to compare sensitivity between players who use different DPI settings.
On its own, yes — higher DPI moves the cursor or camera faster. But when you convert correctly, raising your DPI lowers your in-game sensitivity by the same factor, so your overall (effective) sensitivity stays the same. Higher DPI then just gives the sensor finer steps without changing how far you move to aim.
cm/360 is the physical distance you slide the mouse to turn a full 360° in a game. It depends on DPI, in-game sensitivity, and the game's yaw constant. Because a correct DPI conversion keeps eDPI constant, your cm/360 stays the same too — which is why the converted settings feel identical.
No — that is the whole point. A correct conversion keeps your eDPI and 360° distance unchanged, so muscle memory carries over. The only practical difference is sensor resolution: very low DPI can feel slightly choppy, and extremely high DPI can introduce jitter, so 400–1600 DPI is the usual sweet spot.
Most professional FPS players use 400–800 DPI and adjust in-game sensitivity to taste. This range keeps the sensor accurate while giving enough precision for flick and tracking aim. The best choice is whatever lets you hit your preferred eDPI and 360° distance comfortably on your mousepad.
It depends on the game and your playstyle. As rough competitive ranges: CS2 and Valorant players usually sit around 600–1200 and 200–600 eDPI respectively, while faster games like Apex Legends or Overwatch run higher. Select your game in the calculator and it shows that game's recommended eDPI range and whether your current settings fall inside it.
The Mouse DPI Analyzer measures your mouse's real hardware DPI by comparing physical movement with on-screen pixels. This calculator does the math instead: it converts a known DPI and sensitivity into new equivalent settings. Use the Analyzer to find your true DPI, then use this calculator to convert it.
