Millimolar to mg/ml Conversion Formula:
| From: | To: |
Millimolar to mg/ml conversion is a calculation used in chemistry and biochemistry to convert concentration from millimolar units (mM) to milligrams per milliliter (mg/ml). This conversion is essential for preparing solutions with specific concentrations in laboratory work.
The calculator uses the conversion formula:
Where:
Explanation: The formula converts the molar concentration (millimoles per liter) to mass concentration (milligrams per milliliter) by multiplying by the molecular weight and converting units with the 10⁻³ factor.
Details: Accurate concentration conversion is crucial for preparing chemical solutions, conducting experiments, and ensuring proper dosing in pharmaceutical applications. It bridges the gap between molar-based calculations and mass-based measurements.
Tips: Enter the millimolar concentration and molecular weight values. Both values must be positive numbers. The calculator will automatically compute the concentration in mg/ml.
Q1: Why is this conversion important in laboratory work?
A: Many protocols specify concentrations in mM, but practical preparation often requires measuring mass. This conversion allows researchers to accurately prepare solutions.
Q2: Can this calculator be used for any compound?
A: Yes, as long as you know the molecular weight of the compound, you can use this calculator for any substance.
Q3: What's the difference between mM and mg/ml?
A: mM (millimolar) is a molar concentration unit (millimoles per liter), while mg/ml is a mass concentration unit (milligrams per milliliter).
Q4: How accurate is this conversion?
A: The conversion is mathematically exact. Accuracy depends on the precision of your input values and the accuracy of the molecular weight.
Q5: Can I convert back from mg/ml to mM?
A: Yes, the reverse calculation is: mM = (mg/ml) × 10³ / MW
