Convert Micromoles per hour to Moles per second
Convert Micromoles per hour (µmol/h) to Moles per second (mol/s) instantly and accurately.
Conversion Formula
mol/s = µmol/h × 2.777777778e-10
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.
About Moles per second
The mole per second (mol/s) is the SI coherent derived unit of molar flow rate, numerically equal to the katal (kat) for catalytic activity contexts. Industrial ammonia synthesis (Haber-Bosch) produces ≈50 mol/s of NH₃ per tonne/h output; a large turbine combustion chamber burns natural gas at ≈500 mol/s of CH₄. It is the reference unit in process simulation mass balances. 1 mol/s = 3 600 mol/h = 60 mol/min.
