0.3 nmol/L to ng/mL Converter
Convert any lab value from nmol/L to ng/mL (or back) for 16 hormones and vitamins - pick the molecule below and this calculator uses its exact molecular weight. Also written "nM" or "nmol/l" on some lab reports - 0.3 nM and 0.3 nmol/L mean exactly the same thing.

Each row uses the same value entered above, converted with that molecule's own molecular weight. Custom molecular weight isn't included here since it has no fixed value of its own.
Molar units like nmol/L and mass units like ng/mL aren’t interchangeable without a conversion factor. For Vitamin D, that factor comes from its molecular weight – here’s how it plays out for 0.3 nmol/L.
-> Multiply 0.3 nmol/L by the molecular weight of Vitamin D, 400.64 g/mol: 0.3 × 400.64 = 120.192.
-> Divide that result by 1000 to convert nanomoles to nanograms: 120.192 ÷ 1000 = 0.120192.
0.3 nmol/L converts to 0.120192 ng/mL. The calculator above will do the same math automatically for any value you enter.
