1 ppm = 1,000 ppb = 1,000,000 ppt. Parts Per Billion (ppb). 1 microgram/kilogram (µg/kg) = 1 ppb. 1 microgram/liter (µg/l) = 1 ppb. 1 nanogram/gram (ng/g) = 1 

Best place to compute and convert everything! GET IN TOUCH. Conversion Factors Between ppb and µg m-3 and ppm and mgm-3. On the UK Air Quality Archive, and for reporting data to the European Commission, the appropriate conversion factors at 20oC and 1013 mb are used. Pollutant EC 20 ooC and 1013mb WHO 25 C and 1013mb Ozone 1 ppb = 1.9957 µg m-3 1 ppb … 2011-10-18 Concentrations can also be expressed as parts per million (ppm) or parts per billion (ppb) by using a conversion factor. This conversion factor is based on the molecular weight of the chemical and it is different for every chemical. The temperature of the atmosphere also has an influence on the calculation.

10 ppm to ppb

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: To convert Parts-Per-Million (ppm) to Parts-Per-Billion (ppb), you just need to know that 1ppm is equal to 1000 ppb. With that knowledge, you can solve any other similar conversion problem by multiplying the number of Parts-Per-Million (ppm) by 1000. For example, 3 ppm multiplied by 1000 is equal to 3000 ppb.

This means that the number of parts-per million is calculated by dividing the number of parts-per billion by 1000.
