Conversion Formula
µmol/L = fmol/L × 1.000000000e-9
About Femtomoles per litre
The femtomole per litre (fmol/L, fM) equals 10⁻¹² mol/m³, the standard unit in ultra-sensitive immunoassay, digital ELISA, and LC-MS/MS quantification. Cytokines such as IL-6 occur at 1-100 fmol/L in healthy serum; high-sensitivity cardiac troponin assays report results at this level. 1 fmol/L = 10⁻³ pmol/L = 10⁻¹² mol/m³.
About Micromoles per litre
The micromole per litre (µmol/L, µM) equals 10⁻³ mol/m³, widely used in pharmacology, clinical toxicology, and biochemistry for metabolite and drug concentrations. Serum creatinine: 62-115 µmol/L; uric acid: 200-430 µmol/L; therapeutic phenytoin: 40-80 µmol/L. 1 µmol/L = 10⁻³ mmol/L.
