0.40g/l x 1000 = 400 mg/l = 400ppm Note: The FW of an ion species is equal to its concentration in ppm at 10 -3 M. Fluoride has a FW of 19, hence a 10 -3 M concentration is equal to 19ppm, 1M is equal to 19,000 ppm and 1ppm is equal to 5.2 x 10 -5 M.

One parts per million is equal to 0.998859 milligrams per liter. The unit PPM can be converted into Mg/l by multiplying it with 0.998859.

10 ppm. 45 mg/m3. AFS. 20 ppm. 90 mg/m3. 2,2'-OXIETANOL.

ppm (or ppm m) is used to measure the concentration of a contaminant in soils and sediments.In that case 1 ppm equals 1 mg of substance per kg of solid (mg/kg). ppm (or ppmm) is also sometimes used to describe small concentrations in water, in which case 1 ppm is equivalent to 1 mg/l because a liter of water weighs approximately a 1000 g.

550–950. In relation to the base unit of [density] => (kilograms per cubic meter), 1 Milligrams Per Liter (mg/l) is equal to 0.001 kilograms-per-cubic-meter, while 1 Parts Per  Moles per liter (mol/L) to milligrams per liter (mg/L) to ppm conversion calculator.

This is an abbreviation for "parts per million" and it also can be expressed as milligrams per liter (mg/L).

This last one works because the solution concentration is so low that we can assume the solution density to be 1.00 g/mL. Also, it's this last modification of ppm (the mg/L one) that allows us to go to molarity (which has units of mol/L).
