Enter the initial and final concentrations into the calculator to determine the partial ppm move.

Partial Ppm Move Formula

The following formula is used to calculate the partial PPM (parts per million) move.

PPM = (C1 - C0) / C0 * 10^6


  • PPM is the partial parts per million moveC1 is the final concentration (mg/L) C0 is the initial concentration (mg/L)

To calculate the partial PPM move, subtract the initial concentration from the final concentration. Divide the result by the initial concentration. Multiply the quotient by 10 to the power of 6 to convert the result to parts per million.

How to Calculate Partial Ppm Move?

The following steps outline how to calculate the Partial Ppm Move:

  1. First, determine the initial concentration (C0) in mg/L.
  2. Next, determine the final concentration (C1) in mg/L.
  3. Next, use the formula PPM = (C1 – C0) / C0 * 10^6 to calculate the Partial Ppm Move.
  4. Finally, calculate the Partial Ppm Move.
  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.

Initial concentration (C0) = 25 mg/L

Final concentration (C1) = 40 mg/L
