What is Voltage A / D Calibration ?

We work in Automotive Industry.  We have a embedded product that resides in cars.  There is source code module that reads "NVM Voltage A / D Calibration.  What might this mean ?  Please explain.

The 'C' language function I'm looking at initializes Voltage A / D EEPROM data, reads voltage A / D calibration data from EEPROM.

init functions call another function that reads voltage A / D Calibration data from EEPROM.  My question is what does it mean by A / D calibration data.  Why is it necessary to calibrate A / D data ?
