WebConcentrations in water can also be expressed as parts per million (ppm) or parts per billion (ppb). Occasionally, concentrations of chemicals in water may be written as grams per cubic meter (g/m³). This is the same as grams per 1,000 liters, which may be converted to milligrams per liter (mg/L). Therefore, 1 g/m³ = 1 mg/L = 1 ppm. clang emit ast
