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.
To find the percentage of 130 ppm in a gallon, you need to first convert the ppm (parts per million) to a fraction by dividing by 1,000,000. Then, multiply this fraction by the volume of a gallon (128 oz) and convert the result to a percentage. In this case, 130 ppm in a gallon would be 0.00013 * 128 oz = 0.01664 oz, which is approximately 0.2%.
20000 ppm = 2%
1 gallon = 128 fluid ounces1 oz / 1 gal = 1/128 = 0.0078125 = 7,812.5 x 10-6 = 7,812.5 per million
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.
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.

To dilute 1000 ppm to 500 ppm, you need to add an equal amount of the solution without any concentration. For example, if you have 1 mL of the 1000 ppm solution, you would need to add 1 mL of water to make it 500 ppm.
"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.
