µM → M: M = µM ÷ 1,000,000

FAQ

What is molar concentration?

Molar concentration (molarity) is the amount of substance per unit volume of solution. It's measured in moles per liter (mol/L) or molar (M).

What's the difference between M and mM?

M (molar) is 1 mol/L, while mM (millimolar) is 0.001 mol/L. 1 M = 1000 mM.

What units are supported?

This converter supports molar (M), millimolar (mM), micromolar (µM), nanomolar (nM), picomolar (pM), and moles per liter (mol/L).
