Convert Micromoles per hour to Millimoles per minute
Convert Micromoles per hour (µmol/h) to Millimoles per minute (mmol/min) instantly and accurately.
Conversion Formula
mmol/min = µmol/h × 1.666666667e-5
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 minute
The millimole per minute (mmol/min) equals 10⁻³/60 ≈ 1.667×10⁻⁵ mol/s, the practical unit for metabolic flux in perfused organ systems and for HPLC column loading on preparative scale. A resting human heart consumes ≈3 mmol O₂/min via aerobic metabolism; continuous-flow reaction calorimeters for process safety studies operate at mmol/min feed rates. 1 mmol/min ≈ 1.667×10⁻⁵ mol/s.
