Enter the concentration in mg/ml and the molecular weight in g/mol into the calculator to convert the concentration to millimolar (mM).

Mg/Ml to mM Conversion Formula

The following formula is used to convert a concentration from mg/ml to mM:

C(mM) = (C(mg/ml) / MW(g/mol)) * 1000


  • C(mM) is the concentration in millimolar (mM)
  • C(mg/ml) is the concentration in milligrams per milliliter (mg/ml)
  • MW(g/mol) is the molecular weight in grams per mole (g/mol)

To convert the concentration from mg/ml to mM, divide the concentration in mg/ml by the molecular weight in g/mol and then multiply by 1000.

What is Concentration in mM?

Concentration in millimolar (mM) is a unit of concentration that represents the number of millimoles of a substance in one liter of solution. It is a commonly used unit in chemistry and biochemistry to express the concentration of solutes in a solution.

How to Calculate Concentration in mM?

The following steps outline how to convert the concentration from mg/ml to mM:

  1. First, determine the concentration in mg/ml.
  2. Next, determine the molecular weight of the substance in g/mol.
  3. Use the conversion formula: C(mM) = (C(mg/ml) / MW(g/mol)) * 1000.
  4. Finally, calculate the concentration in mM.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem :

Use the following variables as an example problem to test your knowledge.

Concentration (C(mg/ml)) = 10 mg/ml

Molecular Weight (MW(g/mol)) = 180.16 g/mol (e.g., for glucose)
