Contaminant Concentrations

A liter of water weighs 1000 grams, and a milligram is 1/1,000 th of a gram. Therefore, a milligram of a substance dissolved in a liter of water represents one millionth (1,000 divided by 1/1,000) of the weight, or one part per million (1 ppm).

What does ppm or ppb mean?

One milligram in a kg is 1 ppm (by mass). One liter (L) of pure water at 4 º Cand 1 standard atmosphere pressure weighs exactly 1 kg, so 1 mg/L is 1 ppm.


OPTION X is an adaptation of a procedure originally designed for isolating milligram quantities of highly pure nuclear DNA from tomato (Peterson et al. 1997, 1998).

Understanding Units of Measurement

Likewise, one milligram per cubic meter (mg/m 3) is the same concentration in water as one microgram per liter (ug/L), which is about 1 ppb. Concentrations in Air Concentrations of chemicals in air are typically measured in units of the mass of chemical (milligrams, micrograms, nanograms, or picograms ...
