Pound-moles per hour (lb-mol/h)
Micromoles per hour (µmol/h)

Conversion Formula

µmol/h = lb-mol/h × 453592370

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 Micromoles per hour

The micromole per hour (µmol/h) equals 10⁻⁶/3600 ≈ 2.778×10⁻¹⁰ mol/s, used for photosynthesis gas-exchange measurements, soil respiration CO₂ efflux, and slow metabolic pathway fluxes. Leaf gas analysers (LI-COR, WALZ) report CO₂ assimilation in µmol/h; plant root nutrient uptake studies use µmol/h/g fresh weight. 1 µmol/h ≈ 2.778×10⁻¹⁰ mol/s.
