Enter the total weight (lbs) and the total gallons (gal) into the PPM from Gallons Calculator. The calculator will evaluate the PPM from Gallons. 

PPM from Gallons Formula

The following two example problems outline the steps and information needed to calculate the PPM from Gallons.

PPM = W/G * 119826.427


  • PPM is the PPM from Gallons (parts per million)
  • W is the total weight (lbs) 
  • G is the total gallons (gal) 

To calculate PPM from gallons, divide the weight by the gallons, then multiply by 119826.427.

How to Calculate PPM from Gallons?

The following steps outline how to calculate the PPM from Gallons.

  1. First, determine the total weight (lbs). 
  2. Next, determine the total gallons (gal). 
  3. Next, gather the formula from above = PPM = W/G * 119826.427.
  4. Finally, calculate the PPM from Gallons.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.
