As we know One mol/s is equal to 1000 mmol/s (1 mol/s = 1000 mmol/s).

To convert Mole/Second to Millimole/Second, multiply your mol/s figure by 1000.

Example : convert 25 mol/s to mmol/s:

25 mol/s = 25 × 1000 mmol/s = mmol/s

To convert Millimole/Second to Mole/Second, divide your mmol/s figure by 1000.

Example : convert 25 mmol/s to mol/s:

25 mmol/s = 25 ÷ 1000 mol/s = mol/s
