Convert Millimoles per hour to Micromoles per second
Convert Millimoles per hour (mmol/h) to Micromoles per second (µmol/s) instantly and accurately.
Conversion Formula
µmol/s = mmol/h × 0.2777777778
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.
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.
