17.7 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 - 17.7 nM and 17.7 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.
Turning 17.7 nmol/L into ng/mL takes just two steps once you have the molecular weight of Vitamin D on hand. Here’s the full breakdown.
1) Multiply 17.7 nmol/L by the molecular weight of Vitamin D, 400.64 g/mol: 17.7 × 400.64 = 7091.328.
2) Divide that result by 1000 to convert nanomoles to nanograms: 7091.328 ÷ 1000 = 7.091328.
End result: 17.7 nmol/L = 7.091328 ng/mL. Change the value in the calculator above to convert something else.
