#### How many millimolar in 1 micromolar?

**The answer is 0.001 millimolar.** One micromolar (µM) is one-thousandth of a millimolar (mM), reflecting the relationship between the micro- (10^-6) and milli- (10^-3) prefixes.

#### Measurement Units: Micromolar and Millimolar

**Micromolar (µM)**is a unit of concentration that means one millionth of a molar, or 10^-6 M.**Millimolar (mM)**is a concentration unit denoting one thousandth of a molar, or 0.001 M (10^-3 M).

In the scope of molarity, which is measured in moles per liter:

1 mole/cubic meter equals to:

- 1 millimolar (mM), or
- 1,000 micromolar (µM)

For all critical calculations, check your results carefully; even though our tool is precise, rounding errors may occur.
