Conversion Formula

mmol/h = µmol/h × 0.001

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 hour

The millimole per hour (mmol/h) equals 10⁻³/3600 ≈ 2.778×10⁻⁷ mol/s, standard in clinical chemistry for urine excretion reporting and parenteral nutrition inputs. Creatinine clearance in healthy kidneys averages 8-12 mmol/h; intravenous potassium infusion is clinically limited to ≤10 mmol/h to avoid cardiac arrhythmia. 1 mmol/h ≈ 2.778×10⁻⁷ mol/s.
