Enter the amount of potassium and the amount of creatinine into the Potassium to Creatinine Ratio Calculator. The calculator will evaluate and display the Potassium to Creatinine Ratio. 

Potassium to Creatinine Ratio Formula

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

PCR = P / C *100

  • Where PCR is the Potassium to Creatinine Ratio (%)
  • P is the amount of potassium 
  • C is the amount of creatinine 

How to Calculate Potassium to Creatinine Ratio?

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

Example Problem #1:

  1. First, determine the amount of potassium. 
    • The amount of potassium is given as: 5.
  2. Next, determine the amount of creatinine. 
    • The amount of creatinine is provided as: 20.
  3. Finally, calculate the Potassium to Creatinine Ratio using the equation above: 

PCR = P / C *100

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

PCR = 5 / 20 *100 = 25.00 (%)


Example Problem #2: 

For this problem, the variables required are provided below:

amount of potassium = 6

amount of creatinine = 90

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

PCR = P / C *100 = ?
