  • Conversion of ppm to gallons given a known volume

    How can I calculate the volume of a substance given its concentration in a known volume. Specifically, a substance is present at a concentration of 270,000 ppm in a tank truck of 5,000 gallons. What is that actual volume of the substance? I believe that it could simply be calculated as follows:
    5,000 gal = 0.005 million gallons or MG
    0.005 MG x 270,000 ppm = 1,350 gallons

    Or another way to look at it would be 270,000 ppm = 27%
    27% of 5,000 gal = 1,350 gallons

    Is this correct?

    My question is slightly different. My product is applied at 1:5000, one gallon to every 5,000 gallons. What is the ppm of the one gallon? Thank you!

      Is the 1 gallon 100% some active ingredient? 1 gallon in 5000 gallon is 200 ppm by volume. However, if the gallon itself is some mixture, you might want the concentration of the active ingredient present in the 5000 gallons, not the concentration of the gallon in 5000 gallons.

        Ppm x whole amount (in gallons) devide by 1000000= gallons
