2) Molality; 3) Weight Percent; 4) Mole Fraction; and 5) Parts Per Million or Billion. Weight Percent(or Mass Percent): The weight percent of a solution is

mole fraction or mass fraction. Concentration percentage unit conversion between part per million and gram/kilogram, gram/kilogram to part per million conversion in batch, ppm g/kg conversion chart Difference Between ppm and ppmv ppm vs ppmv Both “ppm” and “ppmv” are abbreviations used in scientific calculations. They are dimensionless quantities. While using these terms one should be very specific and not be confused in using one in place of the other.
