# Convert Mg M3 to PPM?

The exposure limits for chemical vapors in the air are most often given in units of milligrams per cubic meter, as Mg/M3, or parts per million, which is PPM. Units given in mg/m3 describe the maximum amount of mass of a particular chemical which can be present in the air. PPM refers to the volume unites of gas, per 1 million of the same air units. To convert from mg/m3 to ppm, you first need to calculate the gram molecular weight of the chemical you want to convert. A very easy way to do this, without having to go through the steps of the conversion, is to use one of the many free converters that can be found online.

 1. Examine the molecular formula for the chemical for which you are calculating concentration. You can normally find this on the manufacturer's safety data sheet for the chemical. http://www.ehow.com/how_8545242_convert-mgm3-ppm.h...
 What exactly do you want? PPM means parts per million, it is the ratio of two numbers. What are the two numbers you want to compare? Do you mean the SO₂ is mixed with air so http://uk.answers.yahoo.com/question/index?qid=201...
 These formulas can be used when measurements are taken at 25°C and the air pressure is 760 torr (= 1 atmosphere or 760 mm Hg). http://www.ccohs.ca/oshanswers/chemicals/convert.h...
