1 ng/dL = 0.0347 nmol/L. Nothing you type here leaves your browser.
The conversion
- 1 ng/dL = 0.03467 nmol/LFrom ng/dL to nmol/L: divide by 28.84. Back again: multiply by 28.84.
- 1 ng/dL = 0.01 ng/mLFrom ng/dL to ng/mL: divide by 100. Back again: multiply by 100.
Mass and molar units are linked by the molecular weight: 288.4 g/mol (Dehydroepiandrosterone (unconjugated), C19H28O2 (PubChem CID 5881). Labcorp's conversion table uses the same basis: 1 nmol/L = 28.84 ng/dL.). Source: PubChem (NIH).
