Why is the conversion factor 864000 between cmol/s and mmol/d?

Because 1 centimol per second equals 0.01 mol/s, and there are 86400 seconds in a day, multiplying 0.01 mol/s by 86400 seconds gives the equivalent molar amount per day, resulting in 864000 mmol/d.

Can I use this conversion for fluctuating flow rates?

Since cmol/s measures instantaneous flow and mmol/d measures accumulated amounts, flows with high variability should be averaged over time before conversion for accurate results.

In which fields is this unit conversion most relevant?

It is commonly used in chemical engineering, clinical pharmacokinetics, environmental monitoring, and metabolic flux analysis where daily molar totals are needed.

Key Terminology

Centimol per second (cmol/s): A unit of molar flow rate equal to 0.01 moles per second, used to quantify amount of substance passing per unit time in chemical processes.
Millimol per day (mmol/d): A molar flow rate unit representing one thousandth of a mole transferred or consumed over a 24-hour period.
Molar flow rate: The quantity of substance passing through a given point or process per unit time.

Quick Knowledge Check

What does the unit centimol per second (cmol/s) measure?

Amount of substance accumulated over a day

Molar flow rate as amount of substance per second

Metabolic flux over hours

How is millimol per day (mmol/d) defined?

One thousandth of a mole per second

One thousandth of a mole transferred over 24 hours

Amount of substance per minute

Why should flow rates be steady when converting cmol/s to mmol/d?

Because mmol/d measures instantaneous flow

Because cmol/s measures instantaneous flow and mmol/d accumulates over time

Because units are incompatible otherwise
