How it works

Two steps, no account

1

Pick your units

SI-prefixed mol/second variants, or mol/minute, hour, and day for process-scale flows.

2

Enter a value

The result updates instantly as you type, or as soon as you change either unit.

FAQ

Common questions

Is my data sent anywhere?
No. The conversion runs entirely in your browser — nothing is transmitted, logged, or stored.
How is molar flow different from volumetric flow?
Volumetric flow (see the flow rate converter) measures how much space a fluid occupies per unit time; molar flow measures the amount of substance — moles — passing per unit time. The two are related through density and molar mass, which vary by substance.
