2 or CH 4 in terms of parts per million (ppm) or parts per billion (ppb) because the amounts are so small. For example, a concentration of 1 ppm corresponds to 1 part material per 1 million parts of the gas, liquid or solid it is found in. In the case of ppb, the same relationship exists: 1 part material per 1 billion parts of a gas, liquid or

How to convert ppm to ppb. ppm and ppb are defined as: 1ppm = 1/10 6 = 10 -6. 1ppb = 1/10 9 = 10 -9. So. 1ppm = 1000ppb. The number of parts-per billion x ppb is equal to the number of parts-per million x ppm multiplied by 1000: xppb = xppm ⋅ 1000. Example: 7ppm is equal to 7000ppb:

Conversion factors are listed in the table below for a number of substances. 2020-12-05 Currently I am working on NO 2 satellite data in molecules/cm 2 .But I don't know how to convert it to ppm (parts per million). I would be grateful if anyone can give me some suggestions. PPB VOC Gas Sensor. OEM gas sensor with state of the art sensing technology. The MiniPID 2 PPB gas sensor is optimised to deliver an exceptionally low background which allows for optimum low-end sensitivity whilst maintaining a wide dynamic range. Volume mixing ratio: usually ppm - parts per million (10-6); or ppb - parts per billion (10-9); or ppt - parts per trillion (10-12).
