I appreciate the reply djmaxwell, however I am trying to convert from mG to m/s^2, not G, so the factor of 9.8 is necessary in this case. I need to integrate these values for transform approximation purposes.
I have come to notice one thing: regardless of whether FS_XL is 2, 4, 8, or 16, the same sensitivity factor of 0.122 yields the proper value. Can anyone confirm this for me? I reiterate I am using the BerryIMU V3.
