What is the coefficient/multiplier/conversion for mouse acceleration?

Mouse acceleration in Apex is simply "Off" or "On". There is no value slider and I can't find any discussion on what the coefficient might be.

I want to turn off mouse acceleration in-game, but turn it on in my third-party mouse settings at the same value to get the same experience. (I would like to have the same mouse sensitivity and acceleration in different games.*)

If anyone could tell me what the value is, or where to find it, I'd be grateful. 

*Yes I like to play with mouse acceleration on. I am aware this is not the standard but my muscle memory is more suited to this than static sensitivity - I am not asking for unsolicited advice about turning off acceleration. Thank you.
