Parts per million (ppm) signifies the ratio of concentration of a particular substance is dispersed, dissolved , or otherwise within another medium. To answer your question, you would have to know how much of your substance (e.g. 0.0028 gram of common table salt) has been added to one unit of volume (e.g. 1 gram of pure water).
100 ppm is worse than 50 ppm. The higher the ppm value, the more concentrated the substance is in the solution. In this case, a concentration of 100 ppm is twice as much as 50 ppm.
1.61 mole percent is equivalent to 16,100 parts per million (PPM). This conversion is based on the fact that 1 mole percent is equal to 10,000 parts per million.
Mcg (microgram) is a measurement of weight or mass equal to one millionth of a gram, while ppm (parts per million) is a measurement of concentration expressing the amount of one substance in relation to a million units of a whole. In other words, mcg specifies the weight of a substance, while ppm indicates how much of a substance is present in a larger quantity.
To prepare a 0.2 ppm solution from a 1000 ppm solution, you would need to dilute the 1000 ppm solution by adding 5000 parts of solvent for every 1 part of the 1000 ppm solution. This means mixing 1 part of the 1000 ppm solution with 5000 parts of solvent to achieve a 0.2 ppm concentration.
1 percent of H2S is equivalent to 10,000 parts per million (ppm) since ppm is a way to express a concentration, with 1 ppm being equivalent to 0.0001%.
50 ppm is 0.005%
200 ppm is 0.02%
100 ppm is worse than 50 ppm. The higher the ppm value, the more concentrated the substance is in the solution. In this case, a concentration of 100 ppm is twice as much as 50 ppm.
500 ppm.

ppb is not a weight, but a ratio. "parts per billion"
ppm means mg per litre. mg/l means 100ug/dl. Therefore there are 10 x 10 micrograms per decilitre in ppm. In other words, 10ug/dl is 0.1 ppm.
4 g in 1 liter will give you a 4000 ppm solution.
As compared to other fuels, Diesel has much more quantity of sulphur and the quantity of sulphur ranges from 50 ppm - 85 ppm.
1.61 mole percent is equivalent to 16,100 parts per million (PPM). This conversion is based on the fact that 1 mole percent is equal to 10,000 parts per million.
In 2003 carbon dioxide emissions were 370 ppm (parts per million). This year (2013) they reached 400 ppm. At the beginning of the Industrial Revolution they had been 280 ppm for thousands of years.
25 PPM then flushed out properly
