Convert Pound-moles per hour to Femtomoles per hour
Convert Pound-moles per hour (lb-mol/h) to Femtomoles per hour (fmol/h) instantly and accurately.
Conversion Formula
fmol/h = lb-mol/h × 4.535923700e+17
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.
About Femtomoles per hour
The femtomole per hour (fmol/h) equals 10⁻¹⁵/3600 ≈ 2.778×10⁻¹⁹ mol/s, used in slow biological transport studies such as steroid diffusion across lipid bilayers or mineralisation reactions in nanotribology experiments. Passive permeation tests for drug molecules across synthetic membranes reach detection at fmol/h. 1 fmol/h ≈ 2.778×10⁻¹⁹ mol/s.
