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.

For soil, 1 **ppm **= 1 mg/kg of contaminant in soil, and 1 ppb = 1 ug/kg. A measurement of 6 mg/kg is the same as 6 **ppm **or 6,000 ppb, which is equal to 6,000 ug/kg. Concentrations in Water Concentrations of chemicals in water are typically mea-sured in units of the mass of chemical (milligrams, mg or micrograms, ug) per volume of water (liter, L, l).
