About Megamoles per hour

The megamole per hour (Mmol/h) equals 10⁶/3600 ≈ 277.78 mol/s, used for atmospheric chemistry flux estimates and mega-scale industrial chemical throughput. Global annual CO₂ emissions of ≈37 Gt/year correspond to ≈24 Mmol/h; the global ammonia industry produces ≈190 million tonnes/year of NH₃, equivalent to ≈62 Mmol/h. 1 Mmol/h = 10⁶/3600 mol/s ≈ 277.78 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.
