1 µg/L = 13.3476 nmol/L. Nothing you type here leaves your browser.
The conversion
- 1 µg/L = 13.35 nmol/LFrom µg/L to nmol/L: multiply by 13.35. Back again: divide by 13.35.
- 1 µg/L = 0.1 µg/dLFrom µg/L to µg/dL: divide by 10. Back again: multiply by 10.
µg/L and ng/mL give the same number.
Mass and molar units are linked by the molecular weight: 74.922 g/mol (arsenic (As), atomic mass. PubChem lists 74.92159.). Source: PubChem, National Library of Medicine.
Common values
