About Micromoles per cubic metre

The micromole per cubic metre (µmol/m³) equals 10⁻⁶ mol/m³, used in atmospheric science for trace reactive gases. At NTP, 1 ppm (v/v) of a gas ≈ 40 µmol/m³; ambient O₃ at 100 ppb ≈ 4 µmol/m³. Numerically identical to nmol/L. 1 µmol/m³ = 10⁻³ mmol/m³.

About Millimoles per litre

The millimole per litre (mmol/L, mM) equals 1 mol/m³, the dominant unit in clinical chemistry worldwide (SI system). Blood glucose: 3.9-6.1 mmol/L; serum sodium: 135-145 mmol/L; total cholesterol: 3.9-5.2 mmol/L. Numerically identical to mol/m³. 1 mmol/L = 10⁻³ mol/L = 1 mol/m³.
