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.

About Millimoles per day

The millimole per day (mmol/d) equals 10⁻³/86400 ≈ 1.157×10⁻⁸ mol/s, the dominant unit in clinical nutrition and electrolyte balance assessment. Daily recommended intakes: sodium 60-100 mmol/d, potassium 50-70 mmol/d, calcium 20-25 mmol/d. Serum osmolality budgets and 24-hour urine ion excretion panels are routinely reported in mmol/d. 1 mmol/d ≈ 1.157×10⁻⁸ mol/s.
