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.
So, a milligram is one ppm of a kilogram; therefore, one ppm is the same as one mil-ligram per kilogram. â¢ milligram/kilogram or â¢ mg/kg or â¢ 0.001/1,000 or â¢ 10-3/103 38 On Tap Fall 2004 What does ppm or ppb mean? What is ppm and what does it mean? Most contaminants are expressed as parts per million (ppm).This means
