Conversion Formula:
| From: | To: |
The mmol to mg conversion is a fundamental calculation in chemistry, pharmacy, and medical sciences that converts millimoles (a unit of amount of substance) to milligrams (a unit of mass) using molecular weight.
The calculator uses the conversion formula:
Where:
Explanation: This conversion allows you to determine the mass of a substance when you know the number of moles and its molecular weight, bridging the gap between chemical quantity and physical mass.
Details: Accurate conversion between mmol and mg is essential for pharmaceutical dosing, laboratory preparations, chemical reactions, and medical treatments where precise measurements are critical for safety and efficacy.
Tips: Enter the millimole value and molecular weight in g/mol. Both values must be positive numbers. The result will be displayed in milligrams with four decimal places for precision.
Q1: What is the difference between mmol and mg?
A: mmol (millimole) measures the amount of substance (number of particles), while mg (milligram) measures mass. The conversion requires molecular weight to relate these different units.
Q2: Where can I find molecular weight values?
A: Molecular weights can be found in chemical databases, periodic tables, chemical reference books, or calculated from atomic weights of elements in the compound.
Q3: Can this calculator be used for all substances?
A: Yes, as long as you know the correct molecular weight of the substance. The formula applies universally to any chemical compound.
Q4: Why is precision important in these conversions?
A: In medical and pharmaceutical applications, small conversion errors can lead to significant dosing mistakes, potentially affecting treatment outcomes and patient safety.
Q5: How do I convert mg back to mmol?
A: Use the reverse formula: \( mmol = mg \div MW \). Divide the mass in mg by the molecular weight to get the amount in mmol.
