1 µg/L = 0.0127 µmol/L. Nothing you type here leaves your browser.
The conversion
- 1 µg/L = 0.01266 µmol/LFrom µg/L to µmol/L: divide by 78.97. Back again: multiply by 78.97.
- 1 µg/L = 0.1 µg/dLFrom µg/L to µg/dL: divide by 10. Back again: multiply by 10.
Mass and molar units are linked by the molecular weight: 78.97 g/mol (Selenium (Se), atomic weight). Source: PubChem, National Library of Medicine.
Common values
From zero to about twice the usual upper limit, plus the usual limits themselves.
