Convert Moles per hour to Millimoles per second
Convert Moles per hour (mol/h) to Millimoles per second (mmol/s) instantly and accurately.
Conversion Formula
mmol/s = mol/h × 0.2777777778
About Moles per hour
The mole per hour (mol/h) equals 1/3600 mol/s ≈ 2.778×10⁻⁴ mol/s, practical for pilot-plant flow chemistry, laboratory gas manifold flow, and hydrogen production by small electrolysers. A 1 kW alkaline electrolyser at 100% Faradaic efficiency produces ≈18 mol H₂/h; bench-scale packed-bed reactors handle feed rates in mol/h. 1 mol/h ≈ 2.778×10⁻⁴ mol/s ≈ 0.002205 lb-mol/h.
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.
