Sodium & Potassium Ratio Calculator

What is the Sodium-to-Potassium Ratio?

The Sodium-to-Potassium Ratio (Na/K Ratio) is a calculated measure of electrolyte balance in the body. Sodium and potassium play crucial roles in regulating blood pressure, hydration, nerve signaling, and muscle function. Maintaining the right balance between these electrolytes is essential for overall health.

Why is the Sodium-to-Potassium Ratio Important?

The Na/K Ratio provides insights into cardiovascular health, kidney function, and electrolyte imbalances. An abnormal ratio may indicate hypertension, dehydration, or other medical conditions requiring further evaluation.

How is the Na/K Ratio Calculated?

The ratio is calculated using the formula:

Na/K Ratio = Sodium (mEq/L) ÷ Potassium (mEq/L)

If the levels are provided in different units, conversion may be required, although **mmol/L** and **mEq/L** are equivalent for both sodium and potassium:

Conversion:
  Sodium (mEq/L) = Sodium (mmol/L)
  Potassium (mEq/L) = Potassium (mmol/L)

Example Calculation

Inputs:
  Sodium Level: 140 mmol/L
  Potassium Level: 4.5 mmol/L

Calculation:
  Na/K Ratio = 140 ÷ 4.5 = 31.11
