Convert millimolars to molars
1 mM = 0.001 M — exactly. Both units are defined against the SI, so this factor is a fraction, not an approximation.
0.001M
As a fraction: 1/1000
1 mM = 0.001 M
How to convert millimolars to molars
Multiply the number of millimolars by 0.001 to get molars.
The exact factor is 0.001 — as a fraction, 1/1000.
Molar: One mole per liter. The working unit of every wet lab.
