What does 25 ppm mean?

Just as per cent means out of a hundred, so parts per million or ppm means out of a million. Usually describes the concentration of something in water or soil. One ppm is equivalent to 1 milligram of something per liter of water (mg/l) or 1 milligram of something per kilogram soil (mg/kg).

What is ppm in liquid?

Using our abbreviations, one ppm equals one mg/kg. Instead of a kilogram, the unit of liquid volume most commonly used is the liter. A liter of water weighs one kilogram. If the contaminant is a solid, it is measured in milligrams.
