Tools

Mouse Sensitivity Converter

Converts mouse sensitivity settings between different games using each game's yaw value. Enter your DPI and current sensitivity in one game, select a target game, and get the equivalent sensitivity instantly. Supports CS2, Valorant, Overwatch 2, Apex Legends, Fortnite, and many more.

eDPI Calculator

Calculates effective DPI by multiplying mouse DPI by in-game sensitivity. Displays a visual comparison against professional player eDPI ranges for selected games. Useful for comparing aim speed across different hardware and sensitivity configurations.

Polling Rate Tester

Measures your mouse's polling rate in real time by tracking the interval between mouse movement events. Displays the last 5 readings and a live chart of the last 30 readings. Includes a reference table with verdicts for polling rates from 125 Hz to 8000 Hz.

PSA Calculator (Perfect Sensitivity Approximation)

Uses a binary search method to help gamers find their ideal mouse sensitivity. Guides users through a series of A/B comparisons, progressively narrowing the sensitivity range until the optimal value is found.

360° Distance Calculator (cm/360)

Calculates cm/360 and inches/360 — the physical distance your mouse must travel on your mousepad for a full 360-degree in-game rotation. Supports two modes: calculate distance from sensitivity, or find the sensitivity needed for a target distance. Includes a visual scale and pro player reference table.

Click Speed Test (CPS Test)

Measures how fast users can click within a chosen time period (1s, 2s, 5s, or 10s). Calculates CPS (clicks per second) and assigns a rank from Sloth to Inhuman. Includes session history, share/copy features, and guides on clicking techniques like jitter and butterfly clicking.

Frequently Asked Questions

What is GameCalc.gg?

GameCalc.gg is a free website that provides precision tools for PC gamers, including a mouse sensitivity converter, eDPI calculator, polling rate tester, PSA calculator, and 360° distance (cm/360) calculator.

How does the mouse sensitivity converter work?

The converter uses each game's yaw value to translate sensitivity from one game to another. Enter your DPI and current sensitivity in the source game, select the target game, and the tool calculates the equivalent sensitivity.

What is eDPI?

eDPI (effective Dots Per Inch) is calculated by multiplying your mouse DPI by your in-game sensitivity. It provides a single number to compare aim speed across different DPI and sensitivity combinations.

What does the polling rate tester measure?

It measures how frequently your mouse reports its position to your computer, expressed in Hz. Higher polling rates mean more frequent updates and smoother cursor movement. 1000 Hz is the standard for competitive gaming.

What is the PSA Calculator?

The PSA Calculator uses a binary search to help you find your ideal mouse sensitivity through a series of guided A/B comparisons.

What is cm/360?

cm/360 is the physical distance (in centimetres) your mouse must travel on your mousepad for a full 360-degree in-game turn. It is the most universal way to compare sensitivity across different games and DPI settings, because it accounts for both DPI and each game's yaw constant.

Is GameCalc.gg free to use?

Yes. All tools are completely free with no account or registration required.

Which games are supported?

Over 19 popular FPS and competitive games including CS2, Valorant, Overwatch 2, Apex Legends, Fortnite, Arc Raiders, The Finals, Rust, Call of Duty: Warzone, Rainbow Six Siege, Escape from Tarkov, PUBG, Battlefield 2042, Destiny 2, and more. Dedicated per-game pages exist for the most popular titles (e.g. /mouse-sensitivity-converter/cs2, /edpi-calculator/valorant).

How accurate are the calculations?

Sensitivity conversions use official yaw values and are mathematically precise. Polling rate readings may be limited by browser event reporting — for verified readings, use your mouse manufacturer's software.
