The toolkit
- Sensitivity Converter
Move your aim between 13 FPS games — Valorant, CS2, Apex, Overwatch 2, Fortnite and more — with cm/360 matching.
Most used - eDPI Calculator
Your effective DPI in one click, with band comparison against typical competitive ranges.
- cm/360 Calculator
The physical distance your mouse travels per full turn — the one number that survives game swaps.
- FOV Calculator
Convert field of view between 16:9, 4:3, 21:9 and more, with monitor-match factors.
- Mouse DPI Analyzer
Measure what your mouse actually outputs — no driver software, straight from sensor counts.
- Crosshair Generator
Design your crosshair with a live preview; copy style values or export a transparent PNG.
New - Sensitivity Randomizer
Roll practice sensitivities within a chosen band to sharpen mouse control and adaptation.

Why SensForge
- Yaw-based math, not guesswork. Every conversion uses each game's documented rotation constant, with confidence labels on the methodology page.
- Everything runs locally. No uploads, no accounts, no tracking of the settings you enter. Close the tab and nothing persists.
- Built for the way players actually measure. cm/360, eDPI and DPI analysis — the metrics the aim community uses — not vanity numbers.
- Honest limits. Where a yaw value is only single-source or approximate, we say so instead of pretending precision.

Who runs this site
SensForge is an independent, player-run toolset. We build the calculators we wanted while switching between competitive shooters ourselves — read the full story or check the methodology behind every formula.
