In the International System of Units (SI), the coherent unit for molar concentration is mol/m 3. However, most chemical literature traditionally uses mol/dm 3, which is the same as mol/L. This traditional unit is often called a molar and denoted by the letter M, for example: 1 mol/m 3 = 10 −3 mol/dm 3 = 10 −3 mol/L = 10 −3 M = 1 mM = 1 ...

The molar concentration is defined as the amount of a constituent (in moles) divided by the volume of the mixture : =. The SI unit is mol/m 3. However, more commonly the unit mol/L (= mol/dm 3) is used.
The standard SI unit of this quantity is mol/m 3, although more practical units are commonly used, such as mole per liter (mol/L, equivalent to mol/dm 3). For example, the amount concentration of sodium chloride in ocean water is typically about 0.599 mol/L. The denominator is the volume of the solution, not of the solvent.
The concentrations of standard solutions are normally expressed in units of moles per litre (mol/L, often abbreviated to M for molarity), moles per cubic decimetre (mol/dm 3), kilomoles per cubic metre (kmol/m 3), grams per milliliters (g/mL), or in terms related to those used in particular titrations (such as titres).

A strong acid, such as hydrochloric acid, at concentration 1 mol dm −3 has a pH of 0, while a strong alkali like sodium hydroxide, at the same concentration, has a pH of 14. Since pH is a logarithmic scale, a difference of one in pH is equivalent to a tenfold difference in hydrogen ion concentration.
