times in ppb or ppm. ppb (v) is parts per billion by volume (i.e., volume of gaseous pollutant per 109 volumes of ambient air). µg/m3 is micrograms of gaseous pollutant per cubic meter of ambient air. Conversion factors are listed in the table below for a number of substances.

This tutorial gives a bri ระดับ ppm : ระดับ ppb : ระดับ SI Unit: 1 ppm: 1,000 ppb: 1,000 nmol/mol : 10 ppm: 10,000 ppb: 10,000 nmol/mol: 100 ppm: 100,000 ppb: 100,000 nmol/mol: 1,000 ppm: 1,000,000 ppb: 1,000,000nmol/mol X (PPM) = X (PPB) / 1000. This means that the number of parts-per million is calculated by dividing the number of parts-per billion by 1000. How many PPM in a PPB? The conversion factor of parts-per billion to parts-per million is 0.001. 1 PPB = 0.001 PPM. Therefore, there are 0.001parts-per million in one parts-per billion. 4 ppb = 0.004 ppm: 5 ppb = 0.005 ppm: 6 ppb = 0.006 ppm: 7 ppb = 0.007 ppm: 8 ppb = 0.008 ppm: 9 ppb = 0.009 ppm: 10 ppb = 0.01 ppm: 20 ppb = 0.02 ppm: 30 ppb = 0.03 ppm: 40 ppb = 0.04 ppm: 50 ppb = 0.05 ppm: 60 ppb = 0.06 ppm: 70 ppb = 0.07 ppm: 80 ppb = 0.08 ppm: 90 ppb = 0.09 ppm: 100 ppb = 0.1 ppm: 200 ppb = 0.2 ppm: 300 ppb = 0.3 ppm: 400 Free online Fraction conversion.
