Potassium Conversion Formula:
| From: | To: |
The conversion between milliequivalents (mEq) and milligrams (mg) for potassium is essential in medical and nutritional contexts. Since potassium has a valence of 1 and atomic weight of 39, the conversion factor is straightforward: 1 mEq = 39 mg.
The calculator uses the simple conversion formula:
Where:
Explanation: This conversion is based on the atomic weight of potassium (39) and its valence of 1, making the calculation direct and simple.
Details: Accurate potassium measurement is crucial for managing electrolyte balance, prescribing medications, and nutritional planning. Both mEq and mg are commonly used units in clinical practice.
Tips: Enter the potassium value in milliequivalents (mEq). The value must be greater than 0. The calculator will instantly provide the equivalent value in milligrams (mg).
Q1: Why is the conversion factor 39 for potassium?
A: The conversion factor is based on potassium's atomic weight (39) and its valence of 1, following the formula: mg = mEq × atomic weight / valence.
Q2: When would I need to convert potassium mEq to mg?
A: This conversion is commonly needed in medical settings for medication dosing, nutritional labeling interpretation, and laboratory result analysis.
Q3: Is this conversion specific to potassium?
A: Yes, this conversion factor applies only to potassium. Other electrolytes have different conversion factors based on their atomic weights and valences.
Q4: Are there any limitations to this conversion?
A: This conversion is mathematically precise for pure potassium. However, in clinical practice, always consider the specific potassium salt being used (e.g., potassium chloride vs potassium citrate).
Q5: Can I use this calculator for other electrolytes?
A: No, this calculator is specifically designed for potassium. Other electrolytes require different conversion factors based on their atomic weights and valences.
