1 mol/s= 3.6 kmol/h= 60 mol/min= 3600 mol/h
10 mol/s= 36 kmol/h= 600 mol/min= 36000 mol/h
100 mol/s= 360 kmol/h= 6000 mol/min= 360000 mol/h
1000 mol/s= 3600 kmol/h= 60000 mol/min= 3600000 mol/h

Where the mole per second fits

The next smaller molar flow unit is the kilomole per hour (kmol/h). 1 mol/s = 3.6 kmol/h, and 1 kmol/h ≈ 0.2777777778 mol/s.

The next larger molar flow unit is the kilomole per second (kmol/s). 1 mol/s = 0.001 kmol/s, and 1 kmol/s = 1000 mol/s.
