Frequently Asked Questions (FAQs)

1. What is the difference between mg and mEq?
Milligrams (mg) measure the mass of a substance, while milliequivalents (mEq) measure its chemical activity based on the number of ions it can produce. Conversions are necessary when dealing with electrolytes in medical or chemical contexts.

2. How is the mg to mEq conversion calculated?
The conversion formula is:
mEq = (mg × valence) ÷ atomic weight​
Our tool automatically applies this formula using the correct values for each substance.

3. Can I use this tool for substances not listed?
Currently, the tool supports a wide range of common substances. If you need a conversion for a substance not listed, feel free to contact us, and we’ll consider adding it.

4. Is this tool suitable for medical professionals?
Yes! Our mg to mEq calculator is designed for accuracy and ease of use, making it a trusted resource for doctors, pharmacists, and other healthcare providers.

Formula for mEq to mg conversion

To convert milliequivalents (mEq) to milligrams (mg) for a specific substance, you need to account for its molecular weight (MW) and valence (V). The general formula is:

mg = (mEq × MW) / Valence

Where:

  • mg = Mass in milligrams
  • mEq = Number of milliequivalents
  • MW = Molecular weight in grams per mole (g/mol)
  • V = Valence of the substance

This formula adjusts the conversion based on the substance’s chemical properties, ensuring accurate results.

Common 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

Here are some examples:

  • 5 mEq: 5 × 39.1 = 195.5 mg
  • 10 mEq: 10 × 39.1 = 391 mg
  • 20 mEq: 20 × 39.1 = 782 mg

How to Use the mEq to mg Conversion Calculator

The calculator simplifies the process. Follow these steps:

  1. Select the substance (e.g., potassium, calcium).
  2. Enter the mEq value.
  3. Click “Calculate” to get the mg equivalent.

Substances You Can Convert

The calculator supports a variety of substances, each with its own molecular weight and valence:

  • Potassium (K)
  • Calcium (Ca)
  • Magnesium (Mg)
  • Sodium (Na)
  • Chlorine (Cl)
  • Phosphorous (P)
  • Sulfur (S)
  • Sulfate (SO₄)
  • Zinc (Zn)
  • Lithium (Li)
  • Potassium chloride (KCl)
  • Sodium chloride (NaCl)

Since molecular weight and valence differ for each substance, the conversion factor varies. Always choose the correct substance for precise calculations.
