What does mol/second measure?

Mol/second measures the amount of substance in moles passing a point per second, commonly used in chemical and engineering calculations.

When is millimol/day used?

Millimol/day quantifies small amounts of substance transferred or consumed over a 24-hour period in biological, environmental, or chemical processes.

How is the conversion between mol/s and mmol/d calculated?

1 mol/second equals 86400000 millimol/day, so multiply the mol/s value by 86400000 for conversion.

Can this conversion be used for variable flow rates?

This conversion assumes a steady and continuous flow; variable flows may lead to inaccurate daily totals.
