# Electronic – accelerometer accuracy determination

accelerometer

I was looking in to some accelerometer and wondering how I could determine the smallest acceleration change, certain sensors are able to detect. if I wanted to calculated this for example for this accelerometer can I just do it like this:
Sensitivity:5 mV/g noise floor : 35 µV typical (12 mA)
35 *10^-3 /(5/9.81)=> 0.0392 m/s2
assuming we are in the Dynamic measuring range or am I over simplifying this
this not really my area of expertise so I appreciate your help

edit1: back ground info

I’m an aerospace student trying to make a first rough estimation if it would make sense to install a basic of the shell accelerometer (low cost) in order to make a rough drag estimation of the drag acting on a satellite in LEO orbit ( +- 600km) in order to do this I’m interested Measurement level in m/s2 preferably. (the final goal of the mission is to measure temporal gravity changes with a COST GNSS receiver mounted on cube sate the accelerometer will be used to correct for drag)
the accelerometer I have used in my question Is just an example ( the frequency range is way too high) I’m just trying to see how I would get an idea of the acceleration I would be able to measure
