To convert from ppm to mg/Nm3 we work with the top and bottom parts of the above formula separately. We start by converting the 200 moles of SO2 to milligrams (mg), and then we convert the 1 000 000 moles of total gas mixture to normal cubic meters (Nm3). 1. Let’s start by converting the 200 moles of the pollutant SO2 to mg. To do this, we need

To convert percentage to ppm move the decimal point 4 places to the right. Example 1: Determining percentage equivalent of 1 ppm. a. 1 ppm= 1mg/kg= 1 mg/1,000,000 mg c. Convert to % by multiplying by 100 d. 0.000001 x 100 = 0.0001% e. Therefore, 1 ppm is the same as 0.0001%, so to convert ppm to percent divide the ppm by 10,000.
