2.4 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 - 2.4 nM and 2.4 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.
If your report shows 2.4 nmol/L of 25-Hydroxyvitamin D and you need it in ng/mL, the conversion comes down to one formula and two quick calculations.
First, multiply 2.4 nmol/L by the molecular weight of Vitamin D, 400.64 g/mol: 2.4 × 400.64 = 961.536.
Next, divide that result by 1000 to convert nanomoles to nanograms: 961.536 ÷ 1000 = 0.961536.
In short, 2.4 nmol/L is 0.961536 ng/mL. Try a different number in the calculator above to see it recalculate live.
