Enter the total amount of sodium and the total amount of potassium into the Sodium to Potassium Ratio Calculator. The calculator will evaluate and display the Sodium to Potassium Ratio. 

Sodium to Potassium Ratio Formula

The following formula is used to calculate the Sodium to Potassium Ratio. 

SPR = S / P
  • Where SPR is the Sodium to Potassium Ratio (sodium:potassium)
  • S is the total amount of sodium 
  • P is the total amount of potassium 

To calculate the sodium to potassium ratio, simply divide the amount of sodium by the amount of potassium.

How to Calculate Sodium to Potassium Ratio?

The following example problems outline how to calculate Sodium to Potassium Ratio.

Example Problem #1:

  1. First, determine the total amount of sodium.
    • The total amount of sodium is given as: 50.
  2. Next, determine the total amount of potassium.
    • The total amount of potassium is provided as: 500.
  3. Finally, calculate the Sodium to Potassium Ratio using the equation above: 

SPR = S / P

The values given above are inserted into the equation below and the solution is calculated:

SPR = 50 / 500 = .10 : 1 (sodium:potassium)

Example Problem #2: 

For this problem, the variables required are provided below:

total amount of sodium = 60

total amount of potassium = 700

Test your knowledge using the equation and check your answer with the calculator above.

SPR = S / P = ?
