About molar flow rate units

Molar flow rate counts amount of substance per unit time. A pound-mole is the amount whose mass in pounds equals the molecular weight, so 1 lb-mol = 453.59237 mol.

Frequently asked questions

What is the SI unit of molar flow rate?

This converter uses the mole per second (mol/s) as its reference unit; every other unit is defined relative to it.

How many molar flow rate units can I convert?

9 units are supported here, across SI, US customary systems. Every pair can be converted in both directions.

Does this molar flow rate converter work offline?
