inhaled formaldehyde is 800 ppb (0.8 ppm); however, sensitive individuals have reported symptoms at levels around 100 ppb (0.1 ppm) or less. Other studies also have demonstrated that health effects can occur in sensitized individuals at 100 ppb (0.1 ppm) or less for chronic exposures to formaldehyde.

This unit expressed the concentration of a pollutant as the ratio of its volume if segregated pure, to the volume of the air in which it is contained. One part per million (ppm) denotes one part per 1,000,000 (10 6) parts, and a value of 10 −6.

It is also possible to convert ppb to ppm Ppb to ppm converter. 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, 5 ppm multiplied by 1000 is equal to 5000 ppb. ppb to ppm conversion How to convert ppb to ppm.

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.

An atmospheric pressure of 1 atmosphere is assumed. SO 2 1 ppb = 2.62 µg/m 3 NO 2 1 ppb = 1.88 µg/m 3 NO 1 ppb = 1.25 µg/m3 O 3 1 ppb = 2.00 µg/m 3 CO 1 ppb = 1.145 µg/m3 Benzene 1 ppb = 3.19 µg/m3 Parts Per Million (PPM) to Weight Percent (%) Converter. This converter converts parts per million (ppm) to weight percent (%) online.. The parts-per notation is a set of pseudo-units to describe small values of miscellaneous dimensionless quantities, e.g. mole fraction or mass fraction. First Enter the PPM value. Click on the convert tab for the result.
