i need to convert g/km to a ppm reading

im really not sure how to go about this however im preety sure i will need the speed of the vehicle and exhaust gas flow

all i want is an average so if i take speed as 40k/hr however i cannot find an average exhaust flow for a vehicle

any help would be greatly appreciated
