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 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.
