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

Variables:

- 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:

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