Flow - Molar Converter
Convert molar flow rate (the amount of substance flowing per unit time) between moles per second, mole per minute, kilomole per hour and related units.

Quick answer
Molar flow rate counts amount of substance per unit time, in moles per second. One mole per minute is 0.01667 mol/s and one kilomole per hour is 0.2778 mol/s. Chemical engineering works in moles rather than mass because reactions combine in fixed molar ratios regardless of molecular weight.
| Mole per second (mol/s) | 1 |
| Mole per minute (mol/min) | 59.99999988 |
| Mole per hour (mol/h) | 3599.999971 |
| Millimole per second (mmol/s) | 1000 |
| Kilomole per second (kmol/s) | 0.001 |
| Kilomole per hour (kmol/h) | 3.6 |
About the Flow - Molar Converter
Molar flow rate measures the number of moles of a substance passing a point per unit of time. The SI unit is the mole per second.
It is essential in chemical engineering, where reactions are tracked by amount of substance rather than mass or volume.
Frequently Asked Questions
What is molar flow rate?
⌄
It is the number of moles of a substance that flow past a point each unit of time.
Why is molar flow used in chemistry?
⌄
Chemical reactions occur in fixed mole ratios, so tracking molar flow makes reaction and balance calculations straightforward.
What is the SI unit?
⌄
The SI unit is the mole per second (mol/s).
