eDPI Calculator - Sensitivity and cm/360 converter

Compute eDPI, match sensitivity across DPIs, compare setups and estimate cm per 360 with verified yaw data.

eDPI and sensitivity calculator

Private by design: every number is computed in your browser.

Mouse DPI

Counts per inch reported by the mouse, usually 200 to 3200.

In-game sensitivity

Type the number exactly as the game shows it. Never divide by 100 on your own.

New DPI

The DPI you want to switch to while keeping the same feel.

Sensitivity scale

Each game converts sensitivity its own way. Only verified scales unlock cm per 360°.

Source: default m_yaw console variable.

Decimals

Yaw in use: 0.022° per count.

Scale catalog v1, reviewed on 2026-09-23. New games only enter after verification.

Your eDPI

eDPI = 800 × 0.5 = 400

Keep the feel on another DPI

0.25 = 800 × 0.5 ÷ 1600

Centimeters per 360° turn

cm/360 = 914.4 ÷ (800 × 0.5 × 0.022) = 103.91 cm

When this number is valid

Mouse acceleration is off and the same pointer settings apply.
Hipfire on the default field of view: scopes and ADS use separate multipliers this page does not model.
Same scale and camera: the result only compares setups inside one sensitivity scale.

Compare saved setups

Save the current setup, then change the fields and save again. Differences are measured against the first row.

Setup name (optional)

No saved setups yet. Up to 8 setups stay in this browser.

Match this feel in another scale

Converts the current setup so one full turn covers the same physical distance in the target scale.

Target DPI

Target scale

Target sensitivity = 0.5

This page computes numbers only. It never detects your hardware, never changes game settings and never promises aim improvement.

eDPI values are only comparable inside the same scale and settings. There is no cross-game ranking here, and no perfect sensitivity: comfort and consistency beat any single number.

Convert sensitivity with eDPI

Type your mouse DPI — 800 × 0.5 gives 400 eDPI, the worked example used across this page — or pick a quick preset.
Type the in-game sensitivity exactly as the game shows it. This tool never divides percentages by 100 automatically; each scale needs its own documented conversion.
Pick a sensitivity scale. Catalog v1 carries verified yaw data for Counter-Strike 2 (0.022° per count) and Valorant (0.07° per count); anything else uses the generic scale with a manual yaw.
Read the eDPI with the formula and substituted values, then use the swap panel when changing DPI: moving from 800 to 1600 DPI at 0.5 means 0.25 keeps the same 400 eDPI.
Save named setups and compare them side by side, or match the current feel in another scale and DPI through the same physical turn distance.
Copy the text summary or a link that reopens the same setup. Everything runs locally — no settings ever leave your browser.

eDPI questions

What is eDPI?

Effective DPI: mouse DPI multiplied by in-game sensitivity. 800 DPI at 0.5 sensitivity is 400 eDPI. It lets you compare setups only inside the same game scale and settings.

Can I compare eDPI between different games?

Not directly. Each game converts sensitivity its own way, so a single cross-game ranking would mislead. Convert through the same physical turn distance (cm per 360°) and only with a verified yaw on both sides.

Why is cm per 360° hidden?

The angular formula needs a valid yaw: degrees turned per mouse count at sensitivity 1. Catalog games provide it; the generic scale waits for your manual yaw. Without it the page still computes eDPI and same-scale swaps.

Is there a perfect sensitivity?

No, and this page recommends none. Published pro settings are personal choices tied to role, hardware and practice, not verified prescriptions. Pick a comfortable value, then keep it constant while you practice.

Does ADS or scoped sensitivity follow the same number?

No. Scopes and aim-down-sights use separate in-game multipliers that this page does not model. Every result here describes hipfire on default settings.

My game shows sensitivity as a percentage. Do I divide by 100?

Only if that game's own documentation says the percentage maps linearly to the multiplier. This tool applies no automatic percent rule: type the multiplier the scale documents, or use the generic scale with a measured yaw.
