R6 Siege and Apex values cross-checked against independent sources on 20 October 2026.
How do I convert R6 Siege sensitivity to Apex?
To convert R6 Siege sensitivity to Apex, multiply it by 0.2604. R6 Siege turns 0.00572958° per mouse count and Apex turns 0.022°, so R6 Siege 10 becomes Apex 2.604. Keep the same DPI and both settings take 19.9 cm of mouse movement for a full turn.
- Find your R6 Siege sensitivity in the Mouse Sensitivity sliders in the Controls settings (set horizontal and vertical to the same value).
- Multiply it by 0.2604, or type it into the converter above with your DPI.
- In Apex Legends, open Settings → Mouse / Keyboard → Mouse Sensitivity and enter the result.
- Keep the same mouse DPI, or enter your new DPI in the converter.
Going the other way, a typical Apex setting of 1.5 is R6 Siege 5.76, or 34.6 cm per 360° at 800 DPI.

Why R6 Siege and Apex numbers differ
Rainbow Six Siege runs on AnvilNext 2.0 and Apex Legends on Source (modified). Apex numbers are 3.84× smaller than R6 Siege numbers for the same hand movement, because Apex turns more per mouse count.
The in-game slider only takes whole numbers, so round the converted value. Aim-down-sight sensitivity is set separately. Apex Legends grew out of the engine Respawn built for Titanfall 2, a heavily modified version of Source, which is why it kept Source’s 0.022 yaw.
Why does my converted sensitivity feel different?
- Field of view: a wider FOV makes the screen appear to move slower even at the same cm/360.
- Scoped and ADS aim: this matches hipfire only. Apex shares the Source-engine 0.022 yaw, so hipfire sensitivity is identical to CS2. ADS uses separate per-optic multipliers.
- Mouse acceleration: if Windows acceleration or a mouse app adds it, the same movement turns a different amount depending on speed. Turn it off.
Frequently asked questions
What is R6 Siege 10 in Apex?
R6 Siege 10 is Apex 2.604 at the same DPI. Both are 19.9 cm per 360° at 800 DPI.
What is the Apex to R6 Siege multiplier?

Does DPI change the R6 Siege to Apex multiplier?
No. The ×0.2604 multiplier holds at any DPI as long as you use the same DPI in both games. If you change DPI, divide by the ratio of new DPI to old DPI, or enter both values in the converter.
Where do I change sensitivity in Apex Legends?
Go to Settings → Mouse / Keyboard → Mouse Sensitivity. Apex shares the Source-engine 0.022 yaw, so hipfire sensitivity is identical to CS2. ADS uses separate per-optic multipliers.
