mEq to mg conversion Formula
The conversion from mEq to mg depends on the molecular weight (MW) and valence of the substance, The general formula is:
mg = (mEq × MW) / Valence
Where:
- mEq = Milliequivalents
- mg = Milligrams
- MW = Molecular weight (g/mol)
- Valence = Number of charges per ion
Example: Potassium (K)
For potassium (K), the molecular weight is 39.1 g/mol, and its valence is 1 (since it’s a monovalent ion). The formula simplifies to:
mg of potassium = mEq of potassium × 39.1
mEq to mg conversion Table
| mEq Value | Calculation | Result (mg) |
|---|---|---|
| 5 mEq | 5 × 39.1 | 195.5 mg |
| 10 mEq | 10 × 39.1 | 391 mg |
| 20 mEq | 20 × 39.1 | 782 mg |
Tip: Always check the molecular weight and valence for the specific substance to ensure accurate conversion.
