One part per million is about 1 cup of water in a swimming pool. Occasionally, concentrations of chemicals in water may be written as grams per cubic meter (g/m 3). This is the same as grams per 1,000 liters, which may be converted to milligrams per liter (mg/L). Therefore, 1 g/m 3 = 1 mg/L = 1 ppm.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. measurement of 6 mg/L is the same as 6 ppm or 6,000 ppb, which is equal to 6,000 ug/L. A way to visualize one part per billion (ppb) in water is to think of it as one drop in one billion drops of water or about one drop of water in a swimming pool.
The unit â1 ppmâ can be used for a mass fraction if a water-borne pollutant is present at one-millionth of a gram per gram of sample solution. When working with aqueous solutions, it is common to assume that the density of water is 1.00 g/mL. Therefore, it is common to equate 1 gram of water with 1 mL of water.Consequently, ppm corresponds to 1 mg/L and ppb corresponds to 1 Î¼g/L. One part per trillion (ppt) denotes one part per 1,000,000,000,000 parts, one part in 10 12, and a value of 1 Ã 10 â12. 2  This is equivalent to one drop of water diluted into 400 Olympic-size swimming pools (2,500 m 3), or about three seconds out of every hundred thousand years.
