Worked examples
1 µmol/mL equals 1 mM. For NaCl, 1 g/L at 58.44 g/mol is approximately 17.1116 mM. A 25 mg/10 mL solution at 500 g/mol equals 5 mM.

How to use
- Choose source and destination units.
- Enter a value or load an example.
- Add molecular weight only when the converter reveals that field.
Validation and limitations
Incompatible dimensions are rejected. Molecular weight must be positive when required. The converter does not infer density, formula weight, hydrate state, or reagent identity.
