1 pg = 0.0621 fmol. Nothing you type here leaves your browser.
The conversion
- 1 pg = 0.06206 fmolFrom pg to fmol: divide by 16.11. Back again: multiply by 16.11.
Mass and molar units are linked by the molecular weight: 16,114.5 g/mol (Hemoglobin monomer (one heme-globin unit), a quarter of the 64,458 g/mol tetramer. This is the basis labs use when printing MCH in fmol (1 fmol = 16.114 pg; 1 pg = 0.0621 fmol).). Source: Bio-protocol.
