change units

Hi,

two questions: (NX11.0.2) I need to get Body Measurements so that the volume is in cm3 and the weight is in g: is it possible?

Second question: The Help doc says you can set the variable UGII_UNITS_WRITE_FILE, to be able to store new units into a file. But in the env file I didn't find this variable: shall I simply add it to my customized env file? 

Thank you
