Tradeit Calculators

Gaming Calculators

Free calculators for the numbers behind your aim: eDPI, cm/360, the sensitivity that carries between games, and the DPI your mouse actually reports. Plus the CS2 calculators for trade ups and inventory value.

No sign-in and nothing locked. Every result is worked out from your own inputs, and each page shows you how to check it.

Aim and sensitivity

The three numbers behind how your mouse turns the camera, and the tools that measure, compare and carry them between games.

Contracts and skin value. These live in the CS2 tools section and are listed here because people search for them as calculators.

How the aim calculators fit together

Three numbers describe how your mouse turns the camera. DPI is what the sensor reports per inch of desk. eDPI multiplies that by your in-game sensitivity and tells you how fast you are inside one game. cm/360 turns both into a physical distance, which is the only measure that means the same thing in every game.

The calculators here follow that chain. The DPI analyzer checks the first number is real. The eDPI calculator gives you the second and plots it against the range players in your game use. The sensitivity converter holds the third constant when you move between games.

The chain
1 DPI Counts per inch from the sensor. Measure it if you are not sure the number on the box is true.
2 eDPI DPI multiplied by in-game sensitivity. Compares players inside one game.
3 cm/360 Centimetres of desk for one full turn. Compares settings across games.

How the calculators are kept honest
Every formula is stated on its page. Reference ranges and pro settings are dated and sourced, and where a coefficient is unverified the page says so on the output rather than in a footnote.
