Molar Flow Rate Converter
Molar flow rate counts how many moles of a substance pass a point per unit of time. The SI unit is the mole per second. Chemical process design usually works in kilomoles per hour, while laboratory dosing and physiology use millimoles per minute.
26 units supported Base unit mole per second (mol/s)
Multiply the number of moles per second by 3.6 to get kilomoles per hour. How this is calculated
