Enter the molarity and volume into the calculator to determine the amount of substance in millimoles. This calculator can also evaluate any of the variables given the others are known.

M To Mmol Formula

The following formula is used to convert from Molarity (M) to Millimoles (mmol):

mmol = M * V

Variables:

  • mmol is the amount of substance in millimoles (mmol)
  • M is the molarity of the solution (M)
  • V is the volume of the solution (L)

To calculate the amount of substance in millimoles, multiply the molarity of the solution by the volume of the solution. This is because molarity is defined as the amount of substance per unit volume, so multiplying by the volume gives the total amount of substance. Since the result is in moles and we want millimoles, the result is automatically in millimoles because the volume is in liters and 1 M = 1 mol/L.

What is a M To Mmol?

M to Mmol refers to the conversion from molarity (M) to millimoles (mmol). Molarity is a measure of the concentration of a solute in a solution, or of any chemical species, in terms of amount of substance in a given volume. A millimole is one-thousandth of a mole, a unit for amount of substance. Therefore, converting from M to Mmol involves adjusting for the volume of the solution and the scale of the mole unit.

How to Calculate M To Mmol?

The following steps outline how to calculate the amount of substance in millimoles (mmol) using the formula mmol = M * V.


  1. First, determine the molarity of the solution (M).
  2. Next, determine the volume of the solution (L).
  3. Next, use the formula mmol = M * V to calculate the amount of substance in millimoles (mmol).
  4. Finally, calculate the mmol value.
  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.

molarity of the solution (M) = 0.5

volume of the solution (L) = 2
