1 ppb = 0.001 ppm Therefore, there are 0.001parts-per million in one parts-per billion. If you want to determine the number of PPM in one parts-per-billion, simply multiply the number in parts-per-billion by the conversion factor.

We need 1.10 mL of the stock solution diluted to 1.00 L to make a 20.0 ppm solution of HCl. 3) A slightly different form of the above question was answered thusly on Yahoo Answers: The unit "ppm" is equivalent to "mg/L." Concentrated HCl is 12.3 moles/L or, since the molar mass of HCl is 36.5 g/L, 449 g HCl / L. 449 g/L = 449,000 mg/L.

PPM as Percentage: PPM is derived from the fact that the density of water is taken as 1kg/L = 1,000,000 mg/L, and 1mg/L is 1mg/1,000,000mg which is one part in one million (1 PPM). That is 1000 ml is one liter, so that 1 ppm = 1 mg per liter = mg/Liter. Given below is the representation of PPM in percentage.

or writing that in decimal form (without the percent) we'd write 1% = 0.01. Remember next that parts one part per million means 1 in a million, so we can write.
