Convert Micromoles per hour to Millimoles per second
Convert Micromoles per hour (µmol/h) to Millimoles per second (mmol/s) instantly and accurately.
Conversion Formula
mmol/s = µmol/h × 2.777777778e-7
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 Millimoles per second
The millimole per second (mmol/s) equals 10⁻³ mol/s, used in mid-scale continuous-flow chemistry and laboratory reactor design. A syringe pump delivering 10 mL/min of a 6 mmol/L reagent solution delivers 1 mmol/s to the reactor; 1 mmol/s is also the millicatalytic unit (mkat) used as an aggregate activity measure in industrial bioprocess monitoring. 1 mmol/s = 10⁻³ mol/s = 3.6 mol/h.
