1 pg/mL = 0.0051 nmol/L. Nothing you type here leaves your browser.
The conversion
- 1 pg/mL = 0.00507 nmol/LFrom pg/mL to nmol/L: divide by 197.2. Back again: multiply by 197.2.
- 1 pg/mL = 5.07 pmol/LFrom pg/mL to pmol/L: multiply by 5.07. Back again: divide by 5.07.
pg/mL and ng/L give the same number.
Mass and molar units are linked by the molecular weight: 197.23 g/mol (Metanephrine free base, C10H15NO3 (PubChem CID 21100)). Source: National Library of Medicine.
