The number of parts-per million x ppm is equal to the number of parts-per billion x ppb divided by 1000: 1 parts- per million = 1000 parts-per billion. 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 Meant to be used in both the teaching and research laboratory, this calculator (see below) can be utilized to perform dilution calculations when working with solutions having the following concentration units: parts per billion (ppb), parts per million (ppm), parts per thousand (ppt), and parts per hundred (pph, %). This means that there are 500 parts-per-billion in 0.5 parts-per-million.

The conversion factor depends on the temperature at which you want the conversion (usually 25 degrees Centigrade in the US), as well as the ambient pressure. Easily convert Parts Per Trillion (ppt) to Parts Per Billion (ppb) using this free online unit conversion calculator. 0.00000001% = 0.001 ppm = 1 ppb = 1000 ppt (parts per trillion) Without knowing the scale of measurement or what you’re measuring, a reading of 100 of anything lacks any meaning. When it comes to measuring combustible gases, we use a slightly different scale. Parts per million (z angličtiny, česky „dílů či částic na jeden milion“), zkráceně též ppm, je výraz pro jednu miliontinu (celku); někdy je tento výraz odvozován i z latinského pars per milion.

4 ppm to ppb






It's designed for solid performance in routine processes. The M200 pH, mV, S/​cm, S/m, ohm-cm, %HCI, H2SO4 & NaOH, ppb & ppm O2, ppb & ppm Ozone.

So `1 ppm = 1000 ppb or 1 ppb = 10-3 ppm`. The conversion factor depends on the temperature at which you want the conversion (usually 25 degrees Centigrade in the US), as well as the ambient pressure.
