Therefore, 10% is the same as 100,000 parts of a million (ppm). 1% is the same as 10,000 parts per million. This one is important, 1% = 10,000 ppm. Let’s look at some common examples: Oxygen in the air we breathe is 20.9% (or 209,000 ppm) The time-weighted average (TWA) for carbon monoxide is 25 ppm (the same as saying 0.025%)

1% = 1/100. 1ppm = 1/1000000. So. 1ppm = 0.0001%. So to convert from ppm to percent, divide the ppm by 10000: 2007-12-12 2009-08-20 2014-04-10 IUPAC also lists all similar symbols (ppm, ppt, ppb etc.) as deprecated; from IUPAC's “Green Book” [1, p.

It may be expressed as the ratio of the volume of the final diluted solution ( V 2 ) to the initial volume removed from the stock solution ( V 1 ), as shown in the equation above. Microsiemens (μS) is the unit of measurement of electrical conductivity (EC) in water or other liquids.

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 solid.
