100 nmol/L to ng/mL Converter

100 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 - 100 nM and 100 nmol/L mean exactly the same thing.

Molecular weights are cross-checked against PubChem. This tool converts units only - it does not interpret your lab result; always discuss values with your doctor.
Molecular weight 400.64 g/mol. 1 nmol/L = 0.40064 ng/mL.
40.064 ng/mL
100 nmol/L of Vitamin D (25-Hydroxyvitamin D) = 40.064 ng/mL (MW: 400.64 g/mol)

    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 100 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 100 nmol/L by the molecular weight of Vitamin D, 400.64 g/mol: 100 × 400.64 = 40064.
    2) Divide that result by 1000 to convert nanomoles to nanograms: 40064 ÷ 1000 = 40.064.

    In short, 100 nmol/L is 40.064 ng/mL. Try a different number in the calculator above to see it recalculate live.
