29 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 - 29 nM and 29 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.
Here’s a worked example for anyone converting 29 nmol/L of Vitamin D into ng/mL by hand, before double-checking it against the calculator above.
First, multiply 29 nmol/L by the molecular weight of Vitamin D, 400.64 g/mol: 29 × 400.64 = 11618.56.
Next, divide that result by 1000 to convert nanomoles to nanograms: 11618.56 ÷ 1000 = 11.61856.
End result: 29 nmol/L = 11.61856 ng/mL. Change the value in the calculator above to convert something else.
