Then if your calculator has an input for VGA use that 'fella'. Otherwise if you want to be precise and your VGA states the percentage water used - deduct that from the amount of VG you use and put it in a separate entry as water; e.g if you add 4ml of VGA and its a 15% aqueous mix then 0.6ml will be water, 3.2 ml VG - etc etc etc.
thanks for the advice
