Although not specifically addressed here, 1 ppm = 1000 ppb. Concentrations of gaseous pollutants is sometimes given in units of mass per volume, and at other times in ppb or ppm. ppb (v) is parts per billion by volume ( i.e.,  Crystal Clock accuracy is defined in terms of ppm or parts per million and it gives a convenient way of comparing ppm parts per million. ppb parts per billion. Here is a video discussing this type of calculation.

It converts units from ppm to ppb or vice versa with a metric conversion. One ppm is equal to 1000 PPB. We know ppm and ppb are explained as below: 1ppm = 1/106 = 10-6. 1ppb = 1/109 = 10-9. Therefor . 1ppm = 1000ppb. This means! The value of parts-per million ppm is equal to the value of parts-per billion ppb divided by 1000: ppm = ppb / 1000
