An even smaller concentration measurement is parts per billion (ppb). One ppb is one part in 1 billion. One drop of ink in one of the largest tanker trucks used to haul gasoline would be an ink concentration of 1 ppb. It is important to know the difference between ppm and ppb. I hope this helped :)
