Enter the chloride concentration (mg/L) into the Pond Salinity Calculator. The calculator will evaluate the Pond Salinity. 

Pond Salinity Formula

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

PS = .0018066 * CL-


  • 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.

  1. First, determine the chloride concentration (mg/L). 
  2. Next, gather the formula from above = PS = .0018066 * CL-.
  3. Finally, calculate the Pond Salinity.
  4. 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.

chloride concentration (mg/L) = 1.25

PS = .0018066 * CL- = ?
