Molar to Millimolar Converter

Molar to Millimolar Converter

How many millimolar in 1 molar?

The answer is 1,000 millimolar. This is because ‘milli-‘ represents one thousandth, hence there are 1,000 millimolars in one molar concentration.

Measurement Units: Molar and Millimolar

  • Molar (M) is the unit of concentration that is commonly used in chemistry, signifying a mole per liter (mol/L).
  • Millimolar (mM) represents one thousandth of a molar, or 0.001 M (10^-3 M).

In terms of the SI derived unit for molarity (mole per cubic meter):

1 mole/cubic meter corresponds to:

  • 0.001 molar (M), or
  • 1 millimolar (mM)

It is important to ensure accuracy in your conversions. Although our tool is designed for precision, always double-check your results, especially for highly sensitive applications.
