The mg to micromolar (μM) conversion calculates the molar concentration of a solution when you know the mass of the solute in milligrams and its molecular weight. This is essential in chemistry and biochemistry for preparing solutions with specific molar concentrations.
The calculator uses the conversion formula:
Where:
Explanation: The formula converts mass (mg) to amount (μmol) using the molecular weight, then calculates concentration assuming 1 liter of solution.
Details: Accurate concentration calculations are crucial for preparing solutions in research, clinical diagnostics, and pharmaceutical applications where precise molar concentrations are required.
Tips: Enter the mass in milligrams and the molecular weight in g/mol. Both values must be positive numbers. The calculator assumes a final volume of 1 liter.
Q1: What if my solution volume isn't 1 liter?
A: The result is the concentration per liter. For other volumes, divide the result by your actual volume in liters.
Q2: How do I find molecular weight?
A: Molecular weight is the sum of atomic weights in the chemical formula. You can find it in chemical databases or calculate it from the formula.
Q3: What's the difference between μM and mmol/L?
A: 1 mmol/L = 1000 μM. Both are molar concentration units, just different scales.
Q4: Can I use this for any chemical compound?
A: Yes, as long as you know the exact molecular weight of the compound.
Q5: Why multiply by 1000 in the formula?
A: This converts from mmol (from mg/g/mol) to μmol, giving the result in micromolar (μM) units.
