Convert Micromoles per hour to Kilomoles per second
Convert Micromoles per hour (µmol/h) to Kilomoles per second (kmol/s) instantly and accurately.
Conversion Formula
kmol/s = µmol/h × 2.777777778e-13
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 Kilomoles per second
The kilomole per second (kmol/s) equals 1 000 mol/s, characterising the very largest industrial chemical processes. A world-scale ammonia synthesis plant produces ≈3 kmol/s of NH₃; a large steam methane reformer converts natural gas at ≈10 kmol/s. It is the preferred unit in European process simulation when outputs are in the thousands of tonnes per day. 1 kmol/s = 1 000 mol/s = 3 600 kmol/h.
