In science and engineering, the parts-per notation is a set of pseudo-units to describe small values of miscellaneous dimensionless quantities, e.g. mole fraction or mass fraction. Since these fractions are quantity-per-quantity measures, they are pure numbers with no associated units of measurement. Commonly used are parts-per-million (ppm, 10−6), parts-per-billion (ppb, 10−9), parts-per-trillion (ppt, 10−12) and parts-per-quadrillion (ppq, 10−15). This notation is not

As a rule of thumb, once you get above 1,000 ppm, then parts per million is not the right unit of measurement. Convert mol/L to g/L. Molarity is measured in terms of moles per liter (mol/L). 1 ppm = 100 centigrams per cubic meter (cg/m3) 1 ppm = 1.0E-7 centigrams per cubic millimeter (cg/mm3) 1 ppm = 0.1 centigrams per liter (cg/L) 1 ppm = 0.0001 centigrams per milliliter (cg/mL) 1 ppm = 1.0E-6 grams per cubic centimeter (g/cm3) 1 ppm = 0.028316846592 grams per cubic foot (g/ft3) 1 ppm = 1.6387064E-5 grams per cubic inch (g/in3) 1 ppm ppm↔ppb 1 ppm = 1000 ppb ppm↔ppt 1 ppm = 1000000000 ppt ppm↔slug/ft3 1 slug/ft3 = 515378.81852553 ppm » Complete Concentration solution Unit Conversions :: PPM Multicord.
