Convert Micromoles per cubic metre to Picomoles per litre
Convert Micromoles per cubic metre (µmol/m³) to Picomoles per litre (pmol/L) instantly and accurately.
Conversion Formula
pmol/L = µmol/m³ × 1000
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 Picomoles per litre
The picomole per litre (pmol/L, pM) equals 10⁻⁹ mol/m³, the standard unit for most endocrine hormone measurements in clinical chemistry worldwide. Serum free T4: 12-22 pmol/L; oestradiol: 37-530 pmol/L; insulin (fasting): 20-100 pmol/L. Numerically identical to nmol/m³. 1 pmol/L = 10⁻³ nmol/L.
