μM
micromole per liter
Molar concentrationexact by definition
The micromolar is 10⁻⁶ mol/L, or 10⁻³ mol/m³. It is the everyday concentration of biochemistry: enzyme substrates, drug assays and buffer trace components are prepared and quoted in μM, and a typical Michaelis constant lands in the tens of micromolar.
