Convert Picomoles per day to Pound-moles per hour
Convert Picomoles per day (pmol/d) to Pound-moles per hour (lb-mol/h) instantly and accurately.
Conversion Formula
lb-mol/h = pmol/d × 9.185927591e-17
About Picomoles per day
The picomole per day (pmol/d) equals 10⁻¹²/86400 ≈ 1.157×10⁻¹⁷ mol/s, applied in clinical biomarker assays for trace hormones and in isotope-dilution pharmacokinetics. Testosterone circulating at very low concentrations (< 5 pmol/L) with a plasma clearance of 5 L/d yields urinary excretion on the pmol/d scale. 1 pmol/d ≈ 1.157×10⁻¹⁷ mol/s.
About Pound-moles per hour
The pound-mole per hour (lb-mol/h) equals 453.59237/3600 ≈ 0.12600 mol/s, the standard molar flow unit in US chemical process engineering simulation (Aspen Plus, HYSYS, Pro/II). Distillation column feed rates, reactor effluent streams, and compressor suction flows are universally expressed in lb-mol/h in US petrochemical and refinery design. 1 lb-mol/h = 453.59237/3600 mol/s ≈ 0.12600 mol/s ≈ 0.4536 kmol/h.
