10 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 - 10 nM and 10 nmol/L mean exactly the same thing.
Common nmol/L Values

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.
onverting Vitamin D from nmol/L to ng/mL isn’t complicated once you know the molecular weight involved. Here’s the full walkthrough for 10 nmol/L.
Step 1: Multiply 10 nmol/L by the molecular weight of Vitamin D, 400.64 g/mol: 10 × 400.64 = 4006.4.
Step 2: Divide that result by 1000 to convert nanomoles to nanograms: 4006.4 ÷ 1000 = 4.0064.
That’s 4.0064 ng/mL for 10 nmol/L. The calculator above updates instantly if you want to try another value.
