Game Sensitivity Converter: DPI, Yaw and cm/360
Convert sensitivity between console-yaw presets or custom yaw values. See centimetres and inches per full turn and compensate for a DPI change.
Game Sensitivity Converter: DPI, Yaw and cm/360: Preserves the product of yaw, sensitivity and DPI, so the same physical mouse travel produces a full turn. Built-in presets use m_yaw console variables; no community reverse-engineered game factors are supplied. Raw input and no acceleration are assumed.

Match physical mouse travel for a full turn. Use raw input with acceleration disabled; this does not match scoped aim, field of view or on-screen cursor movement.
Formula and custom yaw
cm/360 = 360 ÷ (yaw × sensitivity × DPI) × 2.54
Target sensitivity = current sensitivity × source yaw ÷ target yaw × current DPI ÷ target DPI.
Built-in games use an engine console variable. For other games, or a changed m_yaw, choose Custom yaw and enter a value you trust. Community reverse-engineered values are not supplied.
Source engine console variable
Valve's Source SDK 2013 declares m_yaw with default 0.022 in src/game/client/in_mouse.cpp, line 88. This is the Team Fortress 2 source and the engine reference for the Counter-Strike 2 preset. Accessed 2026-10-04: https://raw.githubusercontent.com/ValveSoftware/source-sdk-2013/master/src/game/client/in_mouse.cpp
Counter-Strike 2 keeps the Source engine's m_yaw default of 0.022. To confirm in your own game, type m_yaw in the developer console; it prints the current value.
Quake console variable
id Software's original Quake source declares m_yaw with default 0.022. Accessed 2026-10-04: https://raw.githubusercontent.com/id-Software/Quake/master/WinQuake/cl_main.c
Rotation distance and units
cm/360 = 360 ÷ (yaw × sensitivity × DPI) × 2.54. The full turn is 360 degrees by definition. NIST Handbook 44 (2009), Appendix C, defines one inch as exactly 2.54 cm. Accessed 2026-10-04: https://www.nist.gov/system/files/documents/2017/05/09/HB44-09-Combined.pdf . Target sensitivity multiplies source sensitivity by source yaw / target yaw and source DPI / target DPI.
How to use it
- Choose the current game or enter a custom yaw, then enter DPI and sensitivity.
- Choose the target game or yaw and the target DPI.
- Read the target sensitivity and physical distance per full turn.

Frequently asked questions
Why do the presets give the same sensitivity at the same DPI?
Their documented default m_yaw values match. Custom yaw supports other engine factors or a console value you have changed.
Why is my game missing?
Built-in numbers are limited to cited engine console variables. For a game with community-derived values, enter a custom yaw you trust.
Does this match scoped aim?
No. Field of view, zoom multipliers, mouse acceleration and operating-system pointer scaling can change perceived or actual behaviour. This calculation matches raw horizontal rotation distance.
Where do the preset yaw values come from?
Team Fortress 2 uses the m_yaw default declared in Valve's Source SDK 2013; Quake's default is declared in id Software's original source. Counter-Strike 2 keeps the Source engine's m_yaw default of 0.022. To confirm in your own game, type m_yaw in the developer console; it prints the current value.
