Convert Micromoles per hour to Micromoles per second
Convert Micromoles per hour (µmol/h) to Micromoles per second (µmol/s) instantly and accurately.
Conversion Formula
µmol/s = µmol/h × 0.0002777777778
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 Micromoles per second
The micromole per second (µmol/s) equals 10⁻⁶ mol/s and is numerically equal to the katal (kat) - the SI unit of catalytic activity. One katal of enzyme converts exactly 1 µmol of substrate per second; preparative HPLC columns and benchtop continuous-flow synthesis reactors commonly operate at µmol/s throughput. 1 µmol/s = 1 µkat = 10⁻⁶ mol/s = 60 µmol/min.
