Millimolar to mg/ml Conversion Formula:
| From: | To: |
The millimolar to mg/ml conversion calculates the mass concentration of a solute in water based on its molar concentration and molecular weight. This is particularly useful in chemistry and biology for preparing solutions with specific concentrations.
The calculator uses the conversion formula:
Where:
Explanation: The formula converts molar concentration to mass concentration by multiplying by the molecular weight and converting units appropriately.
Details: Accurate concentration calculation is essential for preparing chemical solutions, conducting experiments, and ensuring proper dosing in pharmaceutical applications.
Tips: Enter millimolar concentration and molecular weight. Both values must be positive numbers. The calculator assumes the solvent is water.
Q1: Why is this conversion specific to water?
A: The conversion assumes the solvent is water with density approximately 1 g/ml, making mg/ml equivalent to mg/g for practical purposes.
Q2: Can this be used for other solvents?
A: For solvents other than water, additional density corrections may be needed as the conversion assumes density of 1 g/ml.
Q3: What is the precision of this calculation?
A: The precision depends on the accuracy of the input values. The calculator provides results with 4 decimal places.
Q4: Are there limitations to this conversion?
A: This conversion is valid for dilute aqueous solutions where density approximations hold true. For concentrated solutions, additional corrections may be necessary.
Q5: How is this different from molarity to mg/ml conversion?
A: This is essentially the same conversion, but specifically using millimolar units (1 mM = 0.001 M) for convenience in biological and chemical applications.
