## Pond Salinity Formula

The following two example problems outline the steps and information needed to calculate the Pond Salinity.

**PS = .0018066 * CL-**

Variables:

- PS is the Pond Salinity (ppt (parts per thousand))
- CL- is the chloride concentration (mg/L)

## How to Calculate Pond Salinity?

The following steps outline how to calculate the Pond Salinity.

- First, determine the chloride concentration (mg/L).
- Next, gather the formula from above = PS = .0018066 * CL-.
- Finally, calculate the Pond Salinity.
- After inserting the variables and calculating the result, check your answer with the calculator above.
