About molar concentration units
This category covers 8 molar concentration units and every ordered conversion between them, which is 56 dedicated pages in total. The units included here are Mole/Cubic Meter (mol/m³), Molar (mole/liter) (M), Millimolar (mM), Micromolar (µM), Nanomolar (nM), Picomolar (pM), Mole/Liter (mol/L), Millimole/Liter (mmol/L). Each unit is defined against a single canonical reference for the category, so a conversion between any two of them is carried out as two exact steps: the input value is first expressed in the reference unit, then re-expressed in the target unit. Routing every pair through one reference rather than storing a factor for each combination keeps the whole category internally consistent and means a correction to one definition propagates everywhere it is used.
Precision and rounding
Conversions are computed in double-precision floating point and displayed at the precision you choose, so the value shown is a rounded view of a more exact internal result rather than the result itself. Where a factor is defined exactly by treaty or standard, the arithmetic is exact to the limits of the representation; where a factor derives from a measured physical quantity, the trailing digits carry the uncertainty of the underlying measurement. For engineering and scientific work, carry the full precision through intermediate steps and round only the final figure, since rounding at each stage of a multi-step calculation accumulates error.
How to use this page
Pick any pair above to open its dedicated converter, which shows the formula, the exact factor, a table of common values and the source the definition is taken from. The search box filters the pair list by unit name or symbol, which is the quickest route when a category carries many closely named units. Every conversion is calculated in your browser, so pages continue to work offline once visited and no input value is ever sent to a server.
