The conversion between millimoles (mmol) and milligrams (mg) is a fundamental calculation in chemistry and medicine, allowing conversion between molar quantity and mass based on molecular weight.
The calculator uses the conversion formula:
Where:
Explanation: The formula converts the molar quantity to mass by multiplying by the molecular weight and converting grams to milligrams.
Details: Accurate unit conversion is essential for medication dosing, laboratory preparations, and chemical calculations where different measurement systems are used.
Tips: Enter the mmol value and molecular weight (MW) in g/mol. Both values must be positive numbers. The calculator will provide the equivalent mass in milligrams.
Q1: Why multiply by 1000 in the formula?
A: The 1000 converts grams to milligrams (1 g = 1000 mg) since molecular weight is in g/mol.
Q2: Can I use this for any substance?
A: Yes, as long as you know the correct molecular weight of the substance.
Q3: What's the difference between mmol and mol?
A: 1 mmol = 0.001 mol (millimole is one thousandth of a mole).
Q4: How do I find molecular weight?
A: Molecular weight is the sum of atomic weights of all atoms in the molecule, available in periodic tables or chemical references.
Q5: Can I convert mg back to mmol?
A: Yes, use the formula: mmol = mg / (MW × 1000).
