That would be "g" since FS[1:0] may have default value and read value (14 bit) are divided by 4096.0 (This may mean the sensor operated in -2.0g to +2.0g dynamic range).

Accepted Answer
Is there a possibility to change to 4g or 8g mode?
Edit: I found a fork of this lib with functionality to change g-modes. https://developer.mbed.org/users/scohennm/code/MMA8451Q8_1/
