How is 1 mg L equal to 1 ppm?

mg/L = ppm. By definition, a Liter of water weighs 1 kg (1 kilogram or 1000 grams). Therefore 1 mg = 1/1,000,000 of a kg. So, based on what we have learned: 1 mg/L = 1 mg/kg = 1 mg/million mg = ppm.

Also know, what is the relation between ppm and mg L?

as grams per 1,000 liters, which may be converted to mil- ligrams per liter (mg/L). Therefore, 1 g/m3 = 1 mg/L = 1 ppm. Likewise, one milligram per cubic meter (mg/m3) is the same concentration in water as one microgram per liter (ug/L), which is about 1 ppb.

What is 1 ppm?

One liter (L) of pure water at 4ºC and 1 standard atmosphere pressure weighs exactly 1 kg, so 1 mg/L is 1 ppm. Another way to say it is a liter of water weighs 1,000 grams or 1 million mil- ligrams. Therefore, 1 mg in 1 liter is l mg in 1 million mil- ligrams or 1 part per million.
