Conversion Formula

mmol/s = µmol/d × 1.157407407e-8

About Micromoles per day

The micromole per day (µmol/d) equals 10⁻⁶/86400 ≈ 1.157×10⁻¹¹ mol/s, applied in clinical nutrition for micronutrient metabolism and in environmental geochemistry for slow pore-water diffusive fluxes. Iron absorption in the human gut is typically 50-200 µmol/d; zinc urinary excretion is 60-80 µmol/d under normal dietary conditions. 1 µmol/d ≈ 1.157×10⁻¹¹ 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.
