what do mean by vpm (unit of water content in oxygen)

ppm
It is not possible to do so. The term "ppm" refers to parts per million and it requires that the two sets of measurement are the same specified units. For example, a half-and-half mixture by volume, of helium and neon would contain 500,000 ppm of each. But by mass, the same mixture would comprise 165,824 ppm of helium against 834,176 ppm of neon.
ppb is not a weight, but a ratio. "parts per billion"
Parts per Million and Parts per Billion. Parts of a solute per Million parts of the Solvent.
It is a mechanical mixture because of its many parts. :)
0.5Mm = 50 PPM
Multiply ppm by 10000.
322 ppm = 0.0322%
1 GPG = 17.1 PPM
ppm means 1/1,000,000; percent means 1/100. Therefore, every percent is equal to 10,000 ppm. To convert from ppm to percent, you divide by 10,000.ppm means 1/1,000,000; percent means 1/100. Therefore, every percent is equal to 10,000 ppm. To convert from ppm to percent, you divide by 10,000.ppm means 1/1,000,000; percent means 1/100. Therefore, every percent is equal to 10,000 ppm. To convert from ppm to percent, you divide by 10,000.ppm means 1/1,000,000; percent means 1/100. Therefore, every percent is equal to 10,000 ppm. To convert from ppm to percent, you divide by 10,000.
*1000
Today the average concentration of carbon dioxide in the atmosphere is approx. 4oo vpm; some scientists consider that values over 300 ppm are high.
ppm x 3to the power of 6= kg
Divide ppm by 10,000:50,000 / 10,000 = 5 %
Divide by 1000.
Multiply by 10,000: 0.0025 x 10,000 = 25 ppm
