What Is This Tool?
This converter transforms molar flow rates measured in millimol per day into kilomol per second, bridging scales from small biological or environmental flows to large industrial processes.
How to Use This Tool?
-
Enter the molar flow value in millimol per day.
-
Select millimol/day as the input unit and kilomol/second as the output unit.

Examples
-
1000 mmol/d is equivalent to 1.1574074074074e-8 kmol/s
-
5000 mmol/d converts to 5.787037037037e-8 kmol/s
Common Use Cases
-
Reporting drug metabolite excretion rates in clinical pharmacokinetics
-
Expressing nutrient turnover or metabolic fluxes in physiology and biochemistry
-
Quantifying trace pollutant emissions in environmental monitoring
-
Scaling reactant feed rates in large-scale chemical reactors
-
Measuring molar gas flows in industrial pipelines and emission sources
Tips & Best Practices
-
Ensure precise data input to reflect low-rate molar flows accurately.
-
Use appropriate unit selections based on the scale of your application.
-
Consider the differences in time scales when interpreting results.
-
Handle small conversion values carefully to avoid rounding errors.
Limitations
-
Conversions yield extremely small numbers due to scale differences.
-
High-precision tools are needed to measure and calculate these values.
-
Direct conversion from large kilomol/second amounts back to millimol/day is impractical without context.
-
Beware of potential rounding and data interpretation errors.
Frequently Asked Questions
-
What does millimol/day represent in molar flow?
-
Millimol per day quantifies a very small amount of substance, one thousandth of a mole transferred or processed within a 24-hour period.
-
Why convert millimol/day to kilomol/second?
-
To enable comparison and integration of low-rate biological or environmental flows with large industrial-scale molar flow measurements.
-
Are conversions exact or approximate?
-
Conversion is based on a defined rate but involves extremely small values, so careful measurement and calculation are essential.
Key Terminology
-
Millimol per day (mmol/d)
-
A unit representing one thousandth of a mole transferred or processed over a 24-hour period, used for low-rate molar flow measurements.
-
Kilomol per second (kmol/s)
-
An SI unit representing one thousand moles passing a point or being consumed per second, used for large-scale molar flow rates.
-
Molar flow rate
-
The quantity of substance (in moles) flowing through a system or point per unit time.
