ppm↔ug/mg 1 ug/mg = 1000 ppm. ppm↔g/ton 1 ppm = 1 g/ton. 2011-06-15 PPM, also known as Parts per million, is a parameter to measure the quality of a liquid or a substance. In other words it is defined as the measure of a substance in a specific quantity of a solution. In this short tutorial, let us discuss on what is parts per million and how to calculate PPM with simple example.

What is the best set up to find ppm? ppm = mol solute/mass solution × 106 ppm = mass solute/mass solution × 106 ppm = mol solute/mass solvent - the answers to estudyassistant.com This article details the most common methods to quantify the concentration of a component in a mixture, and details how to convert between these concentrations. Concentration is commonly expressed in moles per volume, mass per volume, mass percentage, volume percentage, mole percentage and parts per million.
