1 µmol/L = 1,000 nmol/L. Nothing you type here leaves your browser.

The conversion

  • 1 µmol/L = 1,000 nmol/LFrom µmol/L to nmol/L: multiply by 1,000. Back again: divide by 1,000.
  • 1 µmol/L = 454.4 ng/mLFrom µmol/L to ng/mL: multiply by 454.4. Back again: divide by 454.4.
  • 1 µmol/L = 0.4544 µg/mLFrom µmol/L to µg/mL: divide by 2.201. Back again: multiply by 2.201.

Mass and molar units are linked by the molecular weight: 454.4 g/mol (methotrexate, C20H22N8O5). Source: PubChem, National Library of Medicine.
