14 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 - 14 nM and 14 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.
Converting Vitamin D from nmol/L to ng/mL isn’t complicated once you know the molecular weight involved. Here’s the full walkthrough for 14 nmol/L.
Step 1: Multiply 14 nmol/L by the molecular weight of Vitamin D, 400.64 g/mol: 14 × 400.64 = 5608.96.
Step 2: Divide that result by 1000 to convert nanomoles to nanograms: 5608.96 ÷ 1000 = 5.60896.
14 nmol/L converts to 5.60896 ng/mL. The calculator above will do the same math automatically for any value you enter.
