Millimolar to Milligrams Formula:
| From: | To: |
The millimolar to milligrams conversion is used to calculate the mass of a substance in milligrams from its concentration in millimolar units, molecular weight, and volume. This conversion is essential in chemistry, biochemistry, and pharmaceutical preparations.
The calculator uses the conversion formula:
Where:
Explanation: The formula converts molar concentration to mass by multiplying concentration by molecular weight and volume, then dividing by 1000 to convert from grams to milligrams.
Details: Accurate conversion between concentration units is crucial for preparing solutions, dosing medications, conducting experiments, and ensuring proper chemical reactions in laboratory and clinical settings.
Tips: Enter millimolar concentration in mmol/L, molecular weight in g/mol, and volume in liters. All values must be positive numbers greater than zero for accurate calculation.
Q1: What is the difference between millimolar and molar?
A: Molar (M) is moles per liter, while millimolar (mM) is millimoles per liter. 1 M = 1000 mM.
Q2: Why divide by 1000 in the formula?
A: The division by 1000 converts grams to milligrams, since molecular weight is in g/mol and we want the result in mg.
Q3: Can this calculator be used for any chemical compound?
A: Yes, as long as you know the correct molecular weight of the compound and have the concentration in millimolar units.
Q4: What if my volume is in milliliters instead of liters?
A: Convert milliliters to liters by dividing by 1000 before using the calculator (1 L = 1000 mL).
Q5: How accurate is this conversion?
A: The conversion is mathematically exact. Accuracy depends on the precision of your input values for concentration, molecular weight, and volume.
