Converting Accelerometer Readings to gs?

Hi, I am using an ADXL278 dual-axis accelerometer. I am new to accelerometers so am just looking for some very basic info. I've taken readings with the accelerometer and have the results in volts; I would like to convert these numbers to gs. I see that this is probably something for which I will use the "sensitivity'', but I'm wondering which of the many sensitivity options on the product data sheets I'm supposed to use (min, typ, max). It seems that the "Specifications" page of the ADXL278 data sheets include sensitivity readings for 3 different model numbers and I'm not sure what these are (but am guessing I should use AD22286 since it shows two axes). Could someone please help me understand how I pick sensitivity, or point me to an online resource where I could teach myself about this? Additionally, I would appreciate help understanding temperature-dependence and if/how to factor this into my conversion. Thanks for the help.
