The conversion
- 1 pg/mL = 0.1 ng/dLFrom pg/mL to ng/dL: divide by 10. Back again: multiply by 10.
- 1 pg/mL = 3.467 pmol/LFrom pg/mL to pmol/L: multiply by 3.467. Back again: divide by 3.467.
- 1 pg/mL = 0.003467 nmol/LFrom pg/mL to nmol/L: divide by 288.4. Back again: multiply by 288.4.
Mass and molar units are linked by the molecular weight: 288.43 g/mol (testosterone, C19H28O2). Source: PubChem (National Library of Medicine).
