About these units

The millimole per liter (mM) is a metric unit of molar concentration, equal to 1 moles per cubic meter.

The micromole per liter (µM) is a metric unit of molar concentration, equal to 0.001 moles per cubic meter.

Going the other way, 1 micromole per liter = 0.001 millimoles per liter. Solution strength expressed as moles of solute per unit volume — the working units of every wet lab.
