How to convert from ADC to original analog values? - DEMOQE128

I'm trying to read the accelerometer data off of the DEMOQE128 board through the ADC, and I want to get the original analog voltages from the accelerometer. I'm getting values from 0 - 65535. The ADC is set to output 12 bits and I think the reference voltage is 3V but I could be wrong. Is there some formula or conversion to use to get the original voltages going into the ADC?

Added p/n to subject.
