parts per million) 10 −6: 0,0001%: pphm: liczba części na sto milionów (ang. parts per hundred million) 10 −8: 0,000001%: oznaczenie niezalecane z uwagi na brak równoważnego przedrostka SI ppb (10^-6 : mg/kg= 10^-6 = factor million) Or for PPB: microgram per Kg substance (10^-9) Etc. Since we know that 1 Kg water is 1 liter we can say that for waterous dilutions of an substance PPM is mg per liter. This is OK as long as the density of the waterous solution does not significantly deviates from 1.00 Kg per liter.
