Convert Kilomoles per hour to Moles per second
Convert Kilomoles per hour (kmol/h) to Moles per second (mol/s) instantly and accurately.
Conversion Formula
mol/s = kmol/h × 0.2777777778
About Kilomoles per hour
The kilomole per hour (kmol/h) equals 1000/3600 ≈ 0.27778 mol/s, the dominant molar flow unit in European and international process engineering. Equipment datasheets for distillation columns, heat exchangers, compressors, and chemical reactors all specify flows in kmol/h. A 500 MW gas turbine power plant burns natural gas at ≈50-80 kmol/h. 1 kmol/h ≈ 0.27778 mol/s ≈ 2.205 lb-mol/h.
About Moles per second
The mole per second (mol/s) is the SI coherent derived unit of molar flow rate, numerically equal to the katal (kat) for catalytic activity contexts. Industrial ammonia synthesis (Haber-Bosch) produces ≈50 mol/s of NH₃ per tonne/h output; a large turbine combustion chamber burns natural gas at ≈500 mol/s of CH₄. It is the reference unit in process simulation mass balances. 1 mol/s = 3 600 mol/h = 60 mol/min.
