1 µg/dL = 0.0271 µmol/L. Nothing you type here leaves your browser.

The conversion

  • 1 µg/dL = 0.02714 µmol/LFrom µg/dL to µmol/L: divide by 36.85. Back again: multiply by 36.85.

Mass and molar units are linked by the molecular weight: 368.5 g/mol (DHEA sulfate as the free acid, C19H28O5S (PubChem CID 12594). The sodium salt is 390.5 g/mol, so a lab that calibrates with the salt may use a slightly different factor.). Source: PubChem (NIH).

Common values

From zero to about twice the usual upper limit, plus the usual limits themselves.
