Conversion Formula
fmol/L = nmol/m³ × 1000
About Nanomoles per cubic metre
The nanomole per cubic metre (nmol/m³) equals 10⁻⁹ mol/m³, used in atmospheric chemistry to express trace gas concentrations in air. At NTP, 1 ppb (v/v) of a gas ≈ 40 nmol/m³; indoor benzene at 1 ppb ≈ 40 nmol/m³. Numerically identical to pmol/L. 1 nmol/m³ = 10⁻³ µmol/m³.
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.
