Need a lot more information. Parts per million is a ratio, so we would need the total volume. Could be a few ounces to millions of tons, give or take a few billions.

To calculate the amount of chemical needed per gallon, first determine the total amount of chemical in the 5 gallons of water. Since 16 ounces in 5 gallons equal 500 ppm, you can set up a proportion: (16 ounces/5 gallons) = (x ounces/1 gallon). Solve for x to find out how many ounces of chemical are needed per gallon.
20000 ppm = 2%
3 953 ppm of potassium.
355 parts per million (ppm) is a unitless measurement used to represent concentration. It cannot be directly converted into an imperial weight unit like pounds or ounces.
"ppm" means "parts per million". It's a ratio of two numbers that both have the same unit, so the ratio has no unit. It could be ounces per million ounces inches per million inches seconds per million seconds people per million people . . etc.
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%.
1000 ppm is equivalent to 1 milligram per milliliter.
Jupiter's atmosphere is composed of the following:Molecular hydrogen (H2) - 89.8% (+/- 2.0%)Helium (He) - 10.2% (+/- 2.0%)Methane (CH4) - 3000 ppm (+/- 1000 ppm)Ammonia (NH3) - 260 ppm (+/- 40 ppm)Hydrogen Deuteride (HD) - 28 ppm (+/-10 ppm)Ethane (C2H6) - 5.8 ppm (+/- 1.5ppm)Water (H2O) - 4 ppm (varies with pressure)Small amounts of aerosols, including ammonia ice, water ice, and ammonia hydrosulfide
