Convert millimolars to micromolars
1 mM = 1000 µM — exactly. Both units are defined against the SI, so this factor is a fraction, not an approximation.
1000µM
1 mM = 1000 µM
How to convert millimolars to micromolars
Multiply the number of millimolars by 1000 to get micromolars.
The exact factor is 1000 .
